Question

which statistical test is appropriate for comparing the means of two independent samples?
a. correlation coefficient
b. independent samples t - test
c. chi - square test
d. anova

Explanation:

• Correlation coefficient: Measures the strength and direction of a linear relationship between two variables, not for comparing means of two independent samples.
• Independent samples t - test: Specifically designed to compare the means of two independent groups.
• Chi - square test: Used to test for associations between categorical variables, not for comparing means.
• ANOVA (Analysis of Variance): Compares means of three or more groups. Since the question is about two independent samples, ANOVA is not the most appropriate.

Answer:

B. Independent samples t - test
