Answer to Question 1

B

Answer to Question 2

A correlational design has two measured dependent variables for which we can assess the degree of relationship. A quasi-experimental design has one nonmanipulated independent variable and one measured dependent variable. It is a predictive design as is the correlational design. An experimental design has one manipulated independent variable and one measured dependent variable. It is the only design that allows us to explain a causal relationship.
