A seventh grade English Language Arts teacher wants to order books for all the 37 seventh grade classes. He wants to determine the favorite type of book among the seventh grade students. Which sample would be most appropriate for this survey? A: 7 girls in each of his class 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

Using sampling concepts, it is found that the most adequate sample to determine the favorite type of book among the seventh grade students is given by:

B: every fifth student in the seventh grade.

How are samples classified?

Samples may be classified as:

Convenient: Drawn from a conveniently available pool.

Random: All the options into a hat and drawn some of them.

Systematic: Every kth element is taken.

Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.

Stratified: Also divides the population into groups. Then, a equal proportion of each group is surveyed.

In this problem, we want a sample involving only 7th grade students, considering boys and girls, as to reduce bias, hence the systematic sampling given by option B is the most adequate option.
