Okay, so which of the following is an advantage of using surveys in psychological research? So a reads that they allow researchers to examine phenomena in a highly controlled environment. And while you certainly could use a survey in a highly controlled environment, they're actually useful because you don't need to be in a controlled environment. You can administer a survey to anybody, anywhere, which is really, really useful. So a is not really characteristic of surveys themselves.
B reads that they are not subject to social desirability but that's not true. We know that surveys can be subject to social desirability. People can and do alter their answer choices in order to appear more desirable on surveys all the time. So b can be a potential issue with survey research. C is that they provide in-depth detailed information on unique or rare phenomena.
Now surveys can give us a lot of very useful information, I don't want to downplay that, but they are not the method that is best known for giving us in-depth detailed information. You can only put so many questions on a survey, you can only have so many answer choices, and you can lose some nuance and detail in people's answers because of that format. So c is not really characteristic of surveys either. And then d reads that they allow researchers to collect data from a large number of participants relatively quickly. And that is a wonderful thing about survey research.
You can collect data from thousands of participants in a day, like, with the click of a button. It's extremely useful. So d is a huge advantage of using surveys in psychological research. And there you go.
