Quizplus · Accepted Answer

The t test for related samples requires that participants have been matched on a relevant variable (such as age or gender) and that the normality of the dependent variable has not been violated. However, the independent variable in this type of analysis only has two levels, so option A is incorrect. Therefore, the correct answer is D, which includes options B and C.
