The sample group would need to reflect this same ratio of women to men.
Researchers also suggest that it can improve statistical analysis and allow them to quantify non-responses.
The biggest downside of random sampling is that it can be difficult to obtain.
This punch in of sampling tends to be more costly in terms of money, time, and resources.
Because of this, researchers sometimes have to utilize other sampling methods.
This should help you put the study in perspective.
