Hey Malissa....I'm taking paper 5 too....my teacher told me that we need to know about the standard deviation, standard error, t-test, chi-squared test, null hypothesis and etc....you can find it in your textbook at the appendix...under Statistics....other than that, you'll also need to know how to plan the experiment, determine the manipulated, responding and fixed variable.....besides that, like what sm said, you have to know the syllabus....that's what I can help....do tell me if there are other information that I didn't mention here....
