I discuss two probability sampling methods. These topics differ in the sense that one of them samples groups of people and the other samples individuals. In the presentation, I explain what this means and also list a few examples of these methods of them being used in research.
Thank you very much for explaining this in depth. I was unaware of all the different ways that are used to make sure that the participants are random, however it does make me feel better about studies/experiments in general as it helps me believe they are more accurate than I may believe. Great job!
