Question

The instructor takes her sample by gathering data on five randomly selected students from each Lake Tahoe Community College math class. The type of sampling she used is

a. cluster sampling

b. stratified sampling

c. simple random sampling

d. convenience sampling

Short answer

Because the instructor collects data from five students who were chosen at random, it implies that the instructor is willing to create a stratum of five students. As a result, the instructor might be considered to be employing stratified sampling. As a result, option (b) is completely right.

Step-by-step solution

To find

The type of sampling method used.

Explanation

Each math class has an opportunity to engage in this scenario. To construct a sample, the same number of students from each class are selected. Each math class serves as a stratum for the entire population. This method of stratified sampling selects 5 students from each stratum.

As a result, the correct answer is b. stratified sampling.
