Question

as part of a masters thesis project, a mathematics teacher is interested in the effects of two different te on mathematics achievement. she randomly chooses one class of students to learn an algebraic conce traditional methods and another class of students to learn the same algebraic concept using manipula then compares their test scores. determine whether the samples are dependent or independent.

independent

dependent

Explanation:

To determine if samples are independent or dependent, we check if the selection of one sample affects the other. Here, two different classes (samples) are chosen randomly, with no pairing or connection between the students in each class. Independent samples are when the groups are unrelated, and dependent samples involve paired or related groups (like same subjects tested twice). Since the two classes are separate and randomly selected, the samples are independent.

Answer:

A. Independent
