To ensure the sample is representative of the population as a whole, try to use some random samples.
A sample refers to a small quantity that is examined to get the knowledge of how the whole product/population will be.
Now, we need feedback from our clients. To ensure that our sample is representative of the population as a whole, we should include clients with different attributes.
Like, choosing 10 clients all living in the same place, same gender, and same age group will be the worse sample.
The best way to do this is to select samples randomly, ensuring that our sample includes people with different ages, gender, height, disabilities(if any) and statuses, etc.
So, A randomized sample is the best for ensuring that the sample is representative of the population as a whole.
