Effect Size: Cramer’s V or Phi coefficient is often used as a measure of effect size for chi-square tests, indicating the strength of association between variables. Non-parametric Test: The chi-square test is a non-parametric test, meaning it doesn’t make assumptions about the underlying ...
The two-way chi-square is a test of [{Blank}]. Under what conditions should you use the Chi-Square test for independence? Under what conditions should you use the chi-square test of independence? For either chi-square test, \Sigma(f_e) = n. True False (a) What does a significant ...
The difference between the Chi-square test of homogeneity and the Chi-square test of independence lie in the manner in which the study has been designed. The Chi-square test of homogeneity compares the distribution of a single variable in two o...
Chi-Square Test: Used for categorical data to assess whether there is an association between two variables. Regression Analysis: Used to explore the relationship between a dependent variable and one or more independent variables. It helps predict outcomes and assess the strength of relationships. Make...

In the Chi-square test, when comparing the expected probability (which is calculated from the sample) with the sample measure, why does it suffice to draw conclusions about the population rather than just the sample? I have one last question. In your opinion, if someone performed a Kruskal ...
Explain what the Chi-square test mean. (a) What is the phi coefficient, and when is it used? (b) What does the squared phi coefficient indicate? Explain what is measured by the sum of squares (SS). What does the mean squared error (MSE) measure?

The goodness-of-fit test, which asks a theoretical question such as, “How well does the coin in my hand match a theoretically fair coin?” Note Chi-square analysis is applied to categorical variables and is especially useful when those variables are nominal (where order doesn’t matter, lik...
is just one of many tests used for this purpose. Others may be more appropriate depending on the number of variables or the size of the sample. For example, statisticians use az-testfor data sets with a large sample size. Other testing options include the chi-square test and the f-test...
