Question

A biology teacher wants to know how the students in her department feel about a certain course sequence. She takes a list of students in her department in which the students are numbered as they are listed in alphabetical order. She uses a random number generator to select 40 numbers and interviews the students that those numbers represent in the alphabetical listing. Identify the type of sampling used in this example?

Answer 1

Answer:

Simple random sampling

Step-by-step explanation:

In this example, the teacher takes a random 40-student sample from the whole population of students. The fact that the students are alphabetically order does not interfere in the sampling process since students are picked at random. Therefore, the teacher applied the simple random sampling method.

This method provides an unbiased representation of the population.
