A study is designed to test the effectiveness of a program to teach adolescents about nutrition. All research participants are randomly assigned to two groups, one which goes through the program and the other which does not. Both before and after the program, all participants take a test measuring knowledge of nutrition. What type of experimental design is this? A. posttest-only control group design B. pretest-posttest control group design C. 2 × 2 factorial design D. 2 × 4 factorial design

How does the posttest-only design with non-equivalent groups rectify the disadvantages presented by the one-group posttest-only and the one-group pretest-posttest design? A. By assessing knowledge, attitude, and behaviour B. By including experimental manipulation followed by measurement C. By including a control group D. By adding a pretest to measure the dependent variable
