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?
◦ One-group pretest-posttest
◦ Pretest-posttest control group
◦ Two by two factorial
◦ One-group posttest-only
