10.) Before beginning a unit on frog anatomy, a seventh-grade biology teacher gives each of the
24 students in the class a pre-test to assess their knowledge of frog anatomy. The teacher wants to
compare the effectiveness of an instructional program in which students physically dissect frogs with
the effectiveness of a different program in which students use computer software that only simulates the
dissection of a frog. After completing one of the two programs, students will be given a post-test to
assess their knowledge of frog anatomy. The teacher will then analyze the changes in the test scores
(score on post-test minus score on pre-test).
a. Describe a randomization process for assigning the 24 students to two groups of equal size.
