data collection

I have made my questionnaires for my experiment and have set up this sunday as a time to do it. I will be doing an experiment with 10 people afterwards i am going to take a look at their scores and then individually interview 2-3 of them. My experiment is going to consist of 5 statements with different type of saying like "I am okay with my body" and then having them rate their self esteem then they are going to watch a slide show of beautiful women from magazines and tv shows. Then they will do a similiar questionnaire after to see if their scores go down.
