understanding of what constitutes experimental control (clearly established variables and a solid research question).

This week, we further examined how to read scientific articles. In addition, you should have a solid understanding of what constitutes experimental control (clearly established variables and a solid research question). Read the article from Leaf et al. Download Leaf et al. and identify the following:

1. What is the purpose of the study?
2. What is the independent and dependent variable?
3. What is the experimental question? What kind of experimental question is it?
4. Based on the Discussion section of this article, formulate an original experimental question that could be used as a follow up study.
