Examining the associations between our grouping variables, chi-square tests of independence showed that the proportions of participants with low, respectively high, relationship satisfaction did not differ by gender,χ2(1,N = 875) = 3.24,p = 0.07. Also, there was no significant ass...
The test statistic yields a value of 0.0334 that can be compared against a suitable quantile of the chi-square distribution based on df = 4. If the nominal type-one error rate is set to 0.05, this test does not provide evidence against the null hypothesis. As a result, for this ...

Chi Squareand the Large Enough Sample Condition There are three different tests that use thechi-square; in each test, theassumptions and conditions are the same, including the Large Enough Sample Condition. To know if your sample is large enough to use chi-square, you must check theExpected ...
Automatic detection of sample ratio mismatch in A/B test data If you are using custom statistical software to analyse your A/B tests, the chi square test can easily be added to it as part of the analysis. If you’re using a third-party software you should request they implement this tes...
In this case chi square change was significant but decrease in CFI was low. Although a required component for full factorial invariance35, testing for residual invariance is not a prerequisite for testing mean differences because the residuals are not part of the latent factor, so invariance of ...
There are a number of different chi-square tests, but the two that can seem concerning in this context are the Chi-Square Test of Independence and The Chi-Square Test of Homogeneity. Both have two categorical variables. Both count the the frequencies of the combinations of these categories. ...
