Grace conducts research on race and achievement in mathematics. She designs a study to investigate whether a new intervention she designed increases African-American students' math achievement scores. She randomly assigns college-bound African-American students to the intervention or to a control condition. Grace gives a mathematics achievement test in September to both groups. Through the academic year the treatment condition receives the intervention. She uses end of year achievement tests to see whether there are differences between conditions. Which of the following best represents the design of Grace's study?

Question

Quizplus · Accepted Answer

This design is a pretest-posttest control group design. The control group allows for comparison of the intervention group to a group that did not receive the intervention, while the pretest allows for comparison of the groups' starting achievements before any intervention. The posttest allows for comparison of the groups' end of year achievements.
