B. Systematic sampling
C. Stratified sampling
D. Simple random sampling



Answer :

Final answer:

The type of sampling method being used is stratified sampling, where employees are divided into groups based on departments before being randomly selected for the survey.


Explanation:

Stratified sampling involves dividing the population into groups based on certain characteristics or criteria (strata), and then randomly selecting samples from each group.

In this scenario, where 20 employees from each department are randomly selected to participate in the survey, the method being used is stratified sampling. This is because the employees are divided into strata based on their departments before sampling.

Stratified sampling ensures that each subgroup within the population is represented in the sample proportionally, leading to more accurate results.
