What is the most appropriate statistic for testing the association between categorical independent and quantitative dependent variables? A. Independent sample t-test B. Simple linear regression C. Chi-square test of association D. Paired sample t-test
What is the most appropriate statistic for testing the association between categorical independent and quantitative dependent variables?
A. Independent sample t-test
B. Simple linear regression
C. Chi-square test of association
D. Paired sample t-test
Correct answer is,
A. Independent sample t-test
As Simple linear regression is appropriate when both the dependent and independent variable are quantitative. Hence it is wrong option.
Chi square test for association used when both the variables are categorical variables. Hence it is wrong option.
Paired t test used when their is before after case is arises, for example weight before treatment and weight after treatment. Hence it is wrong answer.
