dentify the variables and the method of analysis to best answer the question. This is a review of t-tests and ANOVAs, as well as independent and dependent variables.

In this assignment, IV= Independent Variable(s) and DV= Dependent Variable(s). When there are IV or DVs note if it is continuous or categorical/dichotomous to help you identify the best method:

IV=

DV=

Best method of analysis=
