Question

If we want to look at the relationship between two categorical variables, we can use ________.

a) T-test
b) ANOVA
c) Chi-squared test
d) Regression analysis

Answer 1

The Chi-squared test is used to analyze the relationship between two categorical variables.

Step-by-step explanation:

If we want to look at the relationship between two categorical variables, we can use the Chi-squared test (option c). The Chi-squared test is a statistical test that helps us determine whether there is a significant association between two categorical variables.

It compares the observed frequencies in each category with the expected frequencies under the assumption of independence. If the test statistic is large enough, we reject the null hypothesis of independence and conclude that there is a relationship between the variables.
