3. The researchers state that they used a "convenience sample". How you understand the sampling method and what do you think will affect the conclusion. What suggestion you can make to improve the experiment design?

4. In your opinion, does the use of a control group make this study an experiment study?  Note: an experiment study controls variables to a much larger degree than an observational study.
