Explain the difference between random sampling and stratified random sampling. Provide an example of each.
What will be an ideal response?
In random sampling, subjects are chosen at random from a larger population. For example, if we defined our population as our current employees, we might assign random numbers to each employee and pick a small group of them for a survey. In stratified random sampling, researchers want to ensure that the balance of groups within the sample is the same as the balance within the population. For example, we might identify the balance of men and women in our organization and ensure our sample has the same balance.
