Question

Provide an appropriate response. As part of a Master's thesis project, a mathematics teacher is interested in the effects of two different teaching methods on mathematics achievement. She randomly chooses a class of students to learn one algebraic concept using traditional methods. Then on another day, the same students learn a similar algebraic concept using manipulatives. The teacher then compares their test scores. Determine whether the samples are dependent or independent. A) independent B) dependent

Explanation / Answer

Here the samples are dependent as the test scores are determined for the same set of students. So even though the sample is chosen is randomly, since the two set of test scores are compared for same set of students, their ability, IQ's ets. will be reflected in both the test scores. So the sets of test scores are not independent. Hence the correct choice is Option(B) dependent. (Ans).
