for my Psychology statistics class, I have to find 3 peer reviewed articles of a research topic and then find something those 3 don't have and make my own hypothetical research article using any tools no matter how expensive they are. make sure the research is an experimental design with a good independent and dependent variable , it doesn't have to be complex you can choose topics like : affects of sleep on exam grade (but not this it's just an example) (sorry I had an issue with the last question please send an invite again)
