1.a). When do researchers use ANOVA vs. Chi-square test? Indicate two main characteristics of ANOVA and Chi-square tests (two for each test).

1.b). What are some of the major limitations of both ANOVA and Chi-square tests? (at least two for each)

When would you use ANOVA instead of a chi-square test? Is it possible to establish through a regression analysis if a variable is a dependent or an independent variable? Why or why not?

When and how do you use a chi-square distribution to test if two variables are independent? What is an example of how to use the contingency table to find expected frequencies?

Identify the type of test (chi-square, t-test, or ANOVA) that we have to use in each of the following scenarios. Explain why you chose that test. We want to compare males and females (gender) based on the difference in time spent on social media (measured as hours per day) We want to compare our customers and the customers of our closest competitors based on their brand loyalty (measured as a Likert scale from 1 to 5) We want to compare...

When we run a chi-square test of independence on a 2x2 table, the resulting Chi-square test statistic would be equal to the square of the Z-test statistic from the Z-test of two independent proportions. True or false

How do you know when to conduct a t-test or a chi-square test?

Explain the Chi-Square test and when it is appropriate.

You will perform a Chi-Square test and an ANOVA test. For each hypothesis test make sure to report the following steps: Identify the null hypothesis, Ho, and the alternative hypothesis, Ha. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed. Find the critical value(s) and identify the rejection region(s). Find the appropriate standardized test statistic. If convenient, use technology. Decide whether to reject or fail to reject the null hypothesis. Interpret the decision in the context of the original...

Chi Square Test We will now use Excel to run an example of a chi square test. Chi square test is checking the independence of two variables. Our example will test if taking hormonal pills and being overweight are related. We will test the independence on 200 random patients. Thus, N=200. They will be divided first into two groups, those who take hormonal pills and those who do not. Second, they will be divided into three groups based on weight,...

1) What’s the difference among the chi-square test for goodness of fit, the chi-square test for independence, and the chi-square test for homogeneity 2) State the requirements to perform a chi-square test

Explain the Chi – Square test and when it is appropriate. Give example of such test.
