which of the following best describes the purpose of anova?
○ measure the strength and direction of a relationship between two variables
○ compare the means of three or more groups
○ determine the relationship between categorical and numerical variables
○ test for the independence of two variables

Explanation:

ANOVA (Analysis of Variance) is used to compare the means of three or more groups to determine if there is a statistically significant difference among them. The first option describes correlation, the third could be regression (for categorical - numerical relationships in some cases but not ANOVA), and the fourth is a chi - square test for independence. So the correct description of ANOVA's purpose is to compare the means of three or more groups.

Answer:

B. Compare the means of three or more groups
