On the other hand, if there is an association between the two variables, there should be a greater number of bald people using one shampoo rather than the other. Just state the p-value, and mention whether it was a one sided or a two sided test. Note that APA style tables do not contain any vertical lines, so do not draw them in or use your word processor to generate them. If you’ve worked with Excel, you’re probably used to seeing all your work on one page, charts, data, and calculations. A chi-square will be significant if the residuals (the differences between observed frequencies and expected frequencies) for one level of a variable differ as a function of another variable. Factor analysis reporting The eight topic factors Six items loaded onto Factor 1. Likelihood Ratio 82. The Chi Square Test. coefficients, proportions, values of t, F and chi square). In our example, we will assume that our scatterplot is the only figure in the Figures section. Chi – Square equals all the sum of the values for stage (5), so we have. ANOVA tests are conducted assuming that the means of the samples analyzed are the same, and creates an "F" statistic used to accept or reject this assumption. SPSS McNemar Test Example. Chapter 13 Chi-Square This section covers the steps for running and interpreting chi-square analyses using the SPSS Crosstabs and Nonparametric Tests. Using SPSS for t Tests. Chi Square allows you to answer important questions with variables measured with nominal or ordinal scales. You will need to copy and paste these into your Application document. Out of 60 respondents, 31. As you can see below, SPSS calculates a number of different measures of association. Thanks to Laura Little, Ph.

Then check my report versus the one you wrote. 112, and p = 0. The chi-square statistic is computed by first computing a chi-square value for each individual cell of the table and then summing them up to form a total chi-square value for the table. 96 is significant at P < 0. Correlations painrelief movement gender. Although the sample size is reasonably large, N =1000, the significance level of. 05, we divide. After conducting a statistical analysis, you should write up the results in proper APA 6th edition style. My guidelines below notwithstanding, the rules on how you present findings are not written in stone, and there are plenty of variations in how professional. In SPSS, each window handles a separate task. Yates' Continuity Corrected Chi-Square Test (2 × 2 Tables) Yates' Continuity Corrected Chi-Square Test (or just Yates' Continuity Correction) is similar to Pearson's chi-square test, but is adjusted for the continuity of the chi-square distribution. It is optional to report the effect size (this does not appear on the SPSS output). The chi square value on the second page of the table are not commonly used. Fortunately, there are other measures of central tendency we can use besides the mean. 05 and power of. 019 Likelihood Ratio 11. APA doesn't say much about how to report regression results in the text, but if you would like to report the regression in the text of your Results section, you should at least present the unstandardized or standardized slope (beta), whichever is more interpretable given the data, along with the t-test and the corresponding significance level. Chi Square Statistic: A chi square statistic is a measurement of how expectations compare to results. txt) or view presentation slides online. The chi-square statistic is computed by first computing a chi-square value for each individual cell of the table and then summing them up to form a total Chi-square value for the table. 2 min, p =.

I have created a sample SPSS regression printout with interpretation if you wish to explore this topic further. 870x​, where x represents height. It should be greater than or equal. DiStefano, C. This section covers specifically how APA style is used to report statistical information or results in various forms in a journal. Chi-square Goodness of Fit Test The chi-square test is designed to test differences whether one frequency is different from another frequency. - Also, notice in this table that we report the results of four separate analyses. Note that APA style tables do not contain any vertical lines, so do not draw them in or use your word processor to generate them. 816 and the p-value = 0. , boxplots for all SES * SES variable groups, and for values on each of the marginal SES variables, and for all cases. Using SPSS to perform Chi-Square tests: Graham Hole, January 2006: page 6: Shudders". Report results 4. R - R is the square root of R-Squared and is the correlation between the observed and predicted values of dependent variable. The following two sections cover the most common statistical tests that make use of the Chi Square. In APA format you do not use the same symbols as statistical formulas. This report will help you to learn about: 1. Usage Note 22565: Testing for differences in a two-way table with a significant chi-square When analysis of a two-way table with multiple rows and/or columns yields a significant chi-square statistic indicating that differences exist among the rows and/or columns, it is usually of interest to perform multiple comparison tests to discover where. The sum of all the Chi Square P values should be 1 if the null hypothesis is true. If you have not violated any assumptions, then report the chi-square statistic, the degrees of freedom, and the P-value. This statistic can be evaluated by comparing the actual value against a critical value found in a Chi-Square distribution (where. Reporting the results of a chi-square test of goodness of fit: A chi-square test of goodness-of-fit was performed to determine whether the three sodas were equally preferred. 5 (page 732) gives areas to the right of the chi-square value, because that’s the p-value in this situation. in Chi square test in SPSS Figure 1: Chi Square test is SPSS Figure 2: Chi Square Test in SPSS. 000; then report p <.

Continue the results section from the previous section; do not start it on a new page. Chi square is used to determine whether a null hypothesis should be rejected or accepted. Introduction to Chi-Square Test (X 2 ) 2. See more ideas about Spss statistics, Research methods and Regression analysis. value from the SPSS output If p-value is less than the significance level, reject Ho. 19, the number of subjects is 90 and the probability is less than. If then statements make a bit more sense renaming a new variable, in order to use in chi square analysis. With the Kruskal-Wallis test, a chi-square statistic SPSS does not report an effect size index for the Kruskal-Wallis test. The actual counts are from observations, the expected counts are typically determined from probabilistic or other mathematical models. The APey Ape is a stickler for APA style. The primary difference between the two is that Fisher's Exact Test is used ONLY when one of the four cells of a 2x2 table has less than five observations. Check out to deal with multicollinearity in SPSS. Multilevel models (MLMs, also known as linear mixed models, hierarchical linear models or mixed-effect models) have become increasingly popular in psychology for analyzing data with repeated measurements or data organized in nested levels (e. - Large chi-squared values mean large deviations from the expected frequencies. Basic guidelines in reporting evaluation results –Organize results such that they clearly answer each evaluation question/objective –Present objective (unbiased), clear, and factual results –Consider using tables or charts to present quantitative results if easier to interpret. 05) of values that are larger than 3.

Recently, a colleague of mine asked for some advice on how to compute interrater reliability for a coding task, and I discovered that there aren’t many resources online written in an easy-to-understand format – most either 1) go in depth about formulas and computation or 2) go in depth about SPSS without giving many specific reasons for why you’d make several important decisions. Chi-squared, more properly known as Pearson's chi-square test, is a means of statistically evaluating data. Next, examine the results of the chi square test generated by a spreadsheet or statistical program. The Chi-square (χ 2) test represents a useful method of comparing experimentally obtained results with those to be expected theoretically on some hypothesis. The number of cells in your table depends on how many levels the variables you chose for analysis had. Most universities today require students to follow APA format in the reporting of statistics and narrative. 0, the stronger the correlation. SPSS: Week 10 1. If sig value > 0. Press Continue when you’ve made the selection. If the actual chi-value from step 4 is equal to or greater than 5. The closer correlation coefficients get to -1. This article describes the basics of chi-square test and provides practical examples using. Chi-square is a “big sample test”, i. He asks 20 participants to try out both products and indicate whether they'd consider buying each products (“yes” or “no”). Returning to our example, before the test, you had anticipated that 25% of the students in the class would achieve a score of 5. " Just fill in the blanks by using the SPSS output. Summary statistics summarize and provide information about your sample data. I've been looking for a statistics resource book that would include guidance in SPSS, because I have started doing research that requires intermediate statistics (that is, statistics beyond the t-test, the ANOVA and the chi-square test), and I couldn't find one for the longest time. It goes through the basics of reporting the results of If I report a chi-square. This easy tutorial will show you how to run the One Way ANOVA test in SPSS, and how to interpret the result in APA Format. So we're going to restrict the comparison to 2×2 tables. Using a χ 2 table, the significance of a Chi-square value of 12. For this step-by-step example, results from an ANOVA analysis were chosen from previous examples in the book. Graham R Gibbs 80,671 views. 08 Sep 2014, 09:28. Next, examine the results of the chi square test generated by a spreadsheet or statistical program. -Then paste the SPSS output for Chi-Square Tests. 05 in the univariate analysis were further used for a multivariate logistic regression analysis. SPSS Statistics Test Procedure in SPSS Statistics. I wrote code as follows: proc freq data = mydata; tables gender*incident*schooltype / chisq; run; However, the output only shows. For example, if I have 3 categorical variables and I want to look at gender and incident by schooltype. He asks 20 participants to try out both products and indicate whether they'd consider buying each products (“yes” or “no”). Based on your SPSS analysis, report the results using correct APA format. I do the shapiro-wilk test in excel and spss. See Chi-square formulae for more details of the mathematics. Please show me step by step SPSS so that i can show the output. It is optional to report the effect size (this does not appear on the SPSS output). 0, as for the Poisson distribution; thus the parameter estimates are unchanged from the Poisson model. The Chi Square distribution is very important because many test statistics are approximately distributed as Chi Square. Use the individual cell contributions to quantify how much of the total chi-square statistic is attributable to each cell's divergence. The degrees-of-freedom are identified, with the sample size, within parentheses, and the p-value should be reported precisely as noted above. We can custom-write anything as well!. Jun 25, 2012 - Interpreting the SPSS Output for a Chi Square Analysis. Typically, if the p-value is 0. 19 and 9556. 05 (fewer than 5 possibilities out of 100 the results were due to chance). 952, and also the p value is not equal, I used Linear Interpolation to calculate, and the p value calculated by linear interpolation is 0. Writing up your results – Guidelines based on APA style. Using SPSS for Nominal Data: Binomial and Chi-Squared Tests. Example 15. 373 indicates that the hypothesis of perfect fit. For example, the log transformed data above has a mean of 1. You can report data from your own experiments by using the template below. This statistical procedure was viewed as the optimal statistical procedure to use because frequency data were present for reading group membership and for gender. 24, df = 1, p =. After deciding what analysis to run (step 1) and running and interpreting the analysis (step 2 and 3) It's time to write up the results in APA format (step 4)! APA Conventions for All Statistical Analyses: The specific numbers and letters to report for each analysis are different. The output from SAS is equal to the results in Table 2. The Pearson's Chi-Square test will assess whether the two cross-tabulated questions are independent or unrelated. Using SPSS to perform Chi-Square tests: Graham Hole, January 2006: page 6: Shudders". 05 (or would I state the exact p value here (. Chi-square, the degrees of freedom, and the probability of the chi-square must always be reported. 0, the stronger the correlation. 4 cm, n=128) and September (38. Now I just simply need to describe each group in terms of those variables and also report if there any significant differences. Step 4 – Write up your results from all three sets of analyses you applied to your data. The chi-square test is designed for use with data on a nominal scale, when all you know about people is the category they're in. Using SPSS for Nominal Data: Binomial and Chi-Squared Tests. He asks 20 participants to try out both products and indicate whether they'd consider buying each products (“yes” or “no”). This function returns the left-tailed probability of the chi-squared distribution indicated. Model – SPSS allows you to specify multiple models in a single regression command. Example 1: A "long" table (4x2) Row variable: Class Rank (4 categories: freshman, sophomore, junior, senior) Column variable: Gender (2 categories: male, female). This is the basic format for reporting a chi-square test result (where the color red means you substitute in the appropriate value from your study). If your scatterplot is the only figure that you are referencing, you can use a 1. For Pearson Correlation, SPSS provides you with a table giving the correlation coefficients between each pair of variables listed, the significance level and the number of cases. A good guideline is to report two. The chi‐square (χ 2 ) test can be used to evaluate a relationship between two categorical variables. First of all we get these two tables (Figure 4. If the test statistic is greater than the upper-tail critical value or less than the lower-tail critical value, we reject the null hypothesis. This test utilizes a contingency table to analyze the data. All statistical symbols are reported in italics: N, SD, M, p, Mdn, r, df, etc. Chi-Square statistics are reported with degrees of freedom and sample size in parentheses, the Pearson chi-square value (rounded to two decimal places), and the significance level: The percentage of participants that were married did not differ by gender, c 2 (1, N = 90) = 0. SPSS: Descriptive and Inferential Statistics 10 The Department of Statistics and Data Sciences, The University of Texas at Austin Section 2: Inferential Statistics 2. DiStefano, C. Otherwise, use the number that your scatterplot corresponds with. Perform a chi square test of independence (using an SPSS two-way contingency table analysis) to determine whether the proportions of work station preferences differ across departments. Below is an example of table format. "Mean total length of brown trout in Sebago Lake increased significantly (3. The t-test using SPSS is simply one of the many statistical tests I can perform for your data. Factor analysis reporting The eight topic factors Six items loaded onto Factor 1. If your audience is unfamiliar with the extensions (beyond SPSS or SAS printouts, see below) to logistic regression, discuss the calculation of the statistics in an appendix or footnote or provide a citation. improve this question. Categorical variables were compared by Chi-square or Fisher exact test. 7 cm, n = 114) 1994. When reporting inferential statistics (e. Graham Hole, Research Skills 2012: page 1 APA format for statistical notation and other things: the chi-square value (rounded to two decimal places), and the significance level: report regression results in the text, but if you would like to report the regression in the text of. If p-value (Asymp. In most cases, this includes the mean and reporting the standard deviation (see below). This is a large number, so your two variables -- the sample's ethnicity and the sample's decision whether or not to buy your product -- are related. Report your results in the APA format and write one to two sentences interpreting your results. 01, and greater than 3. natural log to the bth power, where b is the slope from our logistic regression equation. Report your results in the APA format and write one to two sentences interpreting your results. Report results in APA format. The sum of all the Chi Square P values should be 1 if the null hypothesis is true. For Omnibus Tests of Model Coefficients 25. Results section Remember: all statistics are italicized Be consistent with # of decimal places for each statistic p-values always go to 2 decimal places Do not write 0. Below are the results of two correlations. The probability of observing that value from a random draw of a chi-square distribution with 8 degrees of freedom is 0. The first part indicates the test used—in this case, the. Go to "Datasheet" in SPSS and double click on "var0001. The results are listed in the table on the following page.

SPSS Video Tutorials - Upgrade to View Full Tutorials. , Table 1 displays the) and describe to the reader what should be seen in it. 8 Daily Number (cont) Chi-square goodness of fit statistic: From Table A. It is based on the number of groups present in the categorical variable and the number of continuous discriminant variables. 00005 and greater than zero. We can define quantiles of the chi-square curve just as we did quantiles of the normal curve and Student's t-curve: For any number a between 0 and 1, the a quantile of the chi-square curve with d degrees of freedom, x d,a, is the unique value such that the area under the chi-square curve with d degrees of freedom from minus infinity up to x d,a. The chi-square value for the cell is computed as: (Observed Value - Expected Value)2 / (Expected Value). It is optional to report the effect size (this does not appear on the SPSS output). For those still studying, we'll publish a series of new tutorials and the first of those covers the chi-square goodness-of-fit test. For example, the number of participants in a study should be reported as N = 5, not N = 5. In the grades. Here we will review the correct APA formatting for the most prevalent statistical analyses. Literature Review & Proposal Assignment. Chi-square write-up A chi-square statistic was calculated to examine if there is a preference among four orientations to hang an abstract painting.

The proportion of respondents answering “yes, I'd consider buying this. Of course, our sample size is really too small to tell anything, but this may be useful in the future. Because Q = 31. reliability of the measuring instrument (Questionnaire). Histograms: What are they? How do you make one? Reporting Results. Below are the results of two correlations. IBM SPSS version used: 24. This easy tutorial will show you how to run the One Way ANOVA test in SPSS, and how to interpret the result in APA Format. We have reproduced this table below, with footnotes explaining the percentages. 10, Answer to Mixed ANOVA Guided Example. It is possible to perform ANCOVA using the General Linear Model procedure in SPSS. 612 with 1 and 2 degrees of freedom you would report that as F(1,2) = 36. No matter your level of statistical knowledge, we will get you through oral defense. Use SPSS to calculate a chi-square. As is clear from the above example, calculating Chi Square and testing for significance of hypothesized data in statistics is a painstaking process and demands high accuracy. In a complete report, you would explain if the results supported the hypotheses. This is the basic format for reporting a chi-square test result (where the color red means you substitute in the appropriate value from your study). 042 along with a phi or cramer's v value, how would you suggest I report the results for a Fisher's Exact Test? Finally, would I still report Phi/Cramer's V? spss fishers-exact reporting. sav file, how many people got As, Bs, Cs, Ds, or Fs? See if you can answer so that your sentences still make sense if you skip the numbers, and report frequencies in APA style. Reporting Descriptive Statistics: When reporting descriptive statistic from a variable you should, at a minimum, report a measure of central tendency and a measure of variability. For each word problem, use a solution sheet to solve the hypothesis test problem. You use this test when you have categorical data for two independent variables, and you want to see if there is an association between them. “For the raw score ______, z = _____. For other formats consult specific format guides. However, all letters, like t, M, SD … Continue reading 4 of 4 Basic Steps to Stats: Writing up the Results in. This is a large number, so your two variables -- the sample's ethnicity and the sample's decision whether or not to buy your product -- are related. A Chi-square table of significances is available in many elementary statistics texts and on many Internet sites. I've read how to do this, but the results seem non-sensical. There is always some probability that the results are due to chance alone. org are unblocked. " Enter the data under that variable. It is clear from Table 1 that these six items all relate to difficulty students reported in knowing what to write. For each variable gender and topic, conduct a Chi Square analysis to test if there is an even distribution across each level of each variable (Hint for this test use the Nonparametric Test under the Analyze tab). Once the chi-square statistic is computed, its associated probability - the significance level or p-value, is derived, either using a table or using Excel or SPSS. Categorical variables were compared by Chi-square or Fisher exact test. The latter quotient would be distributed as a chi-squared random variable. The closer the value is to 1, the higher the strength of the association. Perform a chi square test of independence (using an SPSS two-way contingency table analysis) to determine whether the proportions of work station preferences differ across departments. An evaluation of every section will let you plan on your research as you prepare yourself to report it correctly. Still another optimal/optimally idea would be to create the table island with bar dining room style and design. With the Kruskal-Wallis test, a chi-square statistic SPSS does not report an effect size index for the Kruskal-Wallis test. These experiments can vary from two-way tables to multinomial experiments. By default, only one question’s results appears on the screen. One use of "Statistics" is to perform a chi-square test for independence. value from the SPSS output If p-value is less than the significance level, reject Ho. REPORTING INFERENTIAL STATISTICS IN APA FORMAT This guide exists in order to provide guidance on reporting inferential results in psychology assignments. 5 in the numerator), which should make the P value more accurate. Let’s work through and interpret them together. SPSS Statistics Test Procedure in SPSS Statistics. 0098 Then the Likelihood Ratio Chi-Square has reduced from 234. This test utilizes a contingency table to analyze the data. Multinomial Logistic Regression with SPSS The chi-square statistic is the difference in -2 log-likelihoods between the final model and a reduced model. In most cases, this includes the mean and reporting the standard deviation (see below). 000 Step Block Model Step 1 Chi-square df Sig. Using SPSS to Perform a Chi-Square Goodness-of-fit Test The data set consists of two variables: one indicates the categories, and the other the counts for each category. Be sure to include some of your SPSS output in your answer. We will work on R by doing a chi-squared test on the treatment (X) and improvement (Y) columns in treatment. The p -value is the area under the chi-square probability density function (pdf) curve to the right of the specified χ2 value. Exercises Chi Square is a distribution that has proven to be particularly useful in statistics. We show you how to understand these tables of output, what part of this output you need to look at, and how to write up the results in a number of different formats. Use APA style and include a statement about whether you reject or fail to reject the null hypothesis. The chi-square test is designed for use with data on a nominal scale, when all you know about people is the category they're in. Let’s work through and interpret them together. That is, the results indicate significant differential concern for pay versus security. Go to for the chi-square solution sheet. A dialog box will appear (as in Figure 3 of Two Sample t Test: Unequal Variances ). Example: A researcher is interested to learn if there is an association between the treatment. Karl Wuensch's Statistics Lessons. Category: SPSS › APA format for SPSS tables 0 Vote Up Vote Down I want to format my SPSS tables in APA format and i don't know how to do it. Save the SPSS output. Include SPSS syntax and output files in the report. However, its degree of freedom is more than 1, and thus it is not straightforward to convert the chi-squared into the effect size. Provide the decision rule for making this decision. 942, not significant, n. Recall that the one thing t-tests, ANOVA, chi square, and even correlations have in common is that interpretation relies on a p value (p = statistical significance). Variables having P values <0. Understanding Pearson Chi-Square Statistical Technique in Review The Pearson Chi-square (χ2 ) is an inferential statistical test calculated to examine differences among groups with variables measured at the nominal level. Chi-Square Goodness-of-Fit Test Tutorial. 58 is significant at P < 0. 05 and power of. Based on your SPSS analysis, report the results using correct APA format. The chi-square value does not tell us the nature of the differences The Chi-Square Formula. The first stage in configuring SPSS to run Fisher’s exact test is to set up a chi square test. General Formula 3. Generate syntax and output files in SPSS. For Pearson Correlation, SPSS provides you with a table giving the correlation coefficients between each pair of variables listed, the significance level and the number of cases. The Wald test is a test of hypothesis usually performed on parameters that have been estimated by maximum likelihood. ppt), PDF File (. Results Close to two-thirds (61 %) of all the three groups of final year students used one form of CAM or the other with pharmacy (72. If p-value (Asymp. It looks like the 2x2 table is being set up in the wrong order (ie with no disease coming before disease in the first column). Chi is a Greek symbol that looks like the letter x as you can see in the 'chi square formula' image on screen now. We used Chi-square test to examine gender difference between the two groups. What conclusion are you allowed to draw?. , which group performed better?). (2-tailed) t-test for Equality of Means. "), which is all we need to report the result of the Friedman test.

You cannot use a chi-square test on continuous data, such as might be collected from a survey asking people how tall they are. As you do this, SPSS gives you an indication of what the table is going to look like. pdf we find that for both χ² values 0. The output file will appear on your screen, usually with the file name "Output 1. Chi-Square Goodness-of-Fit Test Tutorial. The chi-square test for independence, also called Pearson's chi-square test or the chi-square test of association, is used to discover if there is a relationship between two categorical variables. The idea would be to build the table island with all the work you want. A chi-square will be significant if the residuals (the differences between observed frequencies and expected frequencies) for one level of a variable differ as a function of another variable. First of all, although Chi-Square tests can be used for larger tables, McNemar tests can only be used for a 2×2 table. The relationship between these variables was statistically significant, χ2 (3, N = 2000) = 9. For all regression analyses, some report of effect size should be given for the overall model (such as R2) as well as for the individual predictors (such as converting the F ratios or t ratios associated with each predictor in the final equation to an effect-size r). The Chi Square value of 1. You can transfer more than one dependent variable into this box to analyze many dependent variables at the same time. , students in classrooms). It is based on the number of groups present in the categorical variable and the number of continuous discriminant variables. For each variable gender and topic, conduct a Chi Square analysis to test if there is an even distribution across each level of each variable (Hint for this test use the Nonparametric Test under the Analyze tab). 05 level, this value is in the critical region. It is a nonparametric test. The two tests give the same result. If p-value (Asymp. It uses a Chi-Square test of significance. Chi-Square statistics are reported with degrees of freedom and sample size in parentheses, the Pearson chi-square value (rounded to two decimal places), and the significance level: The percentage of participants that were married did not differ by gender, c 2 (1, N = 90) = 0. Simulation using Excel is used to generate many random samples and calculate the p-value of the test. Generate syntax and output files in SPSS. For example, if you only want to view responses submitted within a certain time frame, create a Filter by Time Period. Research Skills One: Using SPSS 20, Handout 2: Descriptive Statistics: Page 2: into the box and put it near the "columns" graphic. The idea of the test is to compare the sample information (the observed data), with the values that would be expected if the two variables were indeed independent. 26) than in the other two noise conditions (traffic and. But is that just random chance? Or have you found something significant? The Chi-Square Test gives us a "p" value to help us decide. It is clear from Table 1 that these six items all relate to difficulty students reported in knowing what to write. You will then see how the results of the analysis can be reported using APA style. Definition of Chi Square Test: The Chi Square Test is a statistical test which consists of three different types of analysis: Goodness of fit; Test for homogeneity; Test of Independence. Most universities today require students to follow APA format in the reporting of statistics and narrative. The output from SAS is equal to the results in Table 2. For the example here,. The income is divided into three categories: 1(low), 2(medium), and 3(high). Otherwise, use the number that your scatterplot corresponds with. In this blog, I will walk you through recognizing components of an APA-style statistical report so that you will feel more confident reading, interpreting, and writing statistical reports. We have reproduced this table below, with footnotes explaining the percentages. Hi everyone, Question 1 I have a sample of 40 and have run a chi square using SPSS. A Chi-square table of significances is available in many elementary statistics texts and on many Internet sites. To ascertain whether a difference was present in reading group membership (i. 367, but the p value in spss is 0. I've been looking for a statistics resource book that would include guidance in SPSS, because I have started doing research that requires intermediate statistics (that is, statistics beyond the t-test, the ANOVA and the chi-square test), and I couldn't find one for the longest time. See Chi-square formulae for more details of the mathematics. Thank you in advance, Béatrice. Pearson Chi-Square - The chi-square (X²) statistic is used to investigate whether the data from two questions are correlated. , students in classrooms).
