A) a Pearson r test
B) an independent samples t test
C) a paired/related samples t test
D) a linear regression

Question

Quizplus · Accepted Answer

A linear regression is used to predict one variable based on one or more predictor variables. It is specifically designed for predicting the score of one continuous variable from another continuous variable. The other options are not appropriate for this type of analysis. An independent samples t test is used to compare the means of two different groups on a single variable. A paired/related samples t test is used to compare the means of two related groups on a single variable. A Pearson r test is used to assess the strength and direction of the linear relationship between two continuous variables, but it is not designed for predicting one variable from another.
