a seventh grade english language arts teacher wants to order books for all the seventh grade classes. he wants to determine the favorite type of book among the seventh grade students. which sample would be the most appropriate for this survey? a. 7 girls in each of his classes b. every fifth student in the seventh grade c. 1 out of 7 students in his middle school d. all of the boys in one of his seventh grade classes
Answer
Brief Explanations:
A good sample should be representative of the entire seventh - grade student population. Option A only includes girls from each class, which is gender - biased. Option C includes students from the whole middle school instead of just seventh - graders. Option D only includes boys from one class, which is both class - and gender - biased. Option B, every fifth student in the seventh grade, is a form of systematic random sampling that can provide a more representative sample of all seventh - grade students.
Answer:
B. every fifth student in the seventh grade
