The correlated groups t test is used when the independent variable is within subjects in nature, meaning that the same group of participants is measured twice under different conditions. The independent groups t test, on the other hand, is used when the independent variable is between subjects in nature, meaning that two separate groups of participants are compared. Therefore, choice B correctly identifies the nature of the independent variable for each test.
