Well, in that case, you can do an observation study when you watch what people do and take notes. Is this a good method, too? It's a very good method, and it can reveal some interesting results. But don't rely on it because an observation study is you interpreting other people's actions. Therefore you need to combine it with another method. Questionnaires, for example. You've got it. By the way, Mrs. Taylor, what do you think about the Internet as a source of information? Well, what can I say? Of course there is a lot of information available on the Internet, but you can waste a lot of time finding it. Personally, I'd avoid it. Libraries are much better source of information. And librarians are very knowledgeable in their field. So talk to them because they are often the best guide you can have to source information. I agree. Mrs. Taylor, thank you very much for your advice. My pleasure. Good luck with your paper.
