You are working for a research lab. Your principal investigator has asked you to submit a project proposal for a new grant your lab received. Your new grant is to study the effects of a new art therapy program, "Beautiful Easy Easel Solutions," on anxiety. Design an experiment to see if B.E.E.S. is good for anxiety.

1. How will this project assign participants to conditions in a way that reduces the possibility that one group is systematically different from the other? (3)

3. If this project includes an observational measurement after the main independent and dependent variable are introduced, how can the project ensure our rater is not biased in how they rate behavior? (3)

4. If this project includes a survey before the independent variable is introduced, what would be an appropriate format to ask agree/disagree style questions? (3)

5. If this project is influenced by an outside variable that we did not think of that changes our results, what is the term for that outside variable? (3)
