Okay. So what is the main advantage of using a case study in psychological research? Now, without reading through all of these verbatim, we know that the idea behind a case study is to get really rich, in-depth information on a single person or small group of people who are in a unique situation or are sort of a rare case based on their life circumstances or their biology. Based on that, it looks like our answer is going to be b. Now, looking quickly at these other ones as a reminder, case studies, you know, we typically don't have a lot of control over the variables, especially the variables that might have caused that unique situation to happen to the person in the first place.
So that's why a is incorrect. We are typically not looking at large samples with case studies. To get that really rich, in-depth amount of information, we're usually only going to be studying one person or a very small group of people. And then finally, the data from a case study itself cannot necessarily be generalized to the broader population. The information that we learn in a case study can then be tested in different ways in laboratories and verified that way, but we don't want to just take the data from a case study and then automatically assume that it can be generalized to other people.
We want to verify that through other methods. So based on that, our answer here is b.
