Question

Andria wants to conduct an experiment to determine whether a new medication is effective in reducing swelling. Explain to Andria the best sampling method, what statistics she should study, and what conclusions she can draw from the experiment.

Answer 1

my answer: Swelling is a very common thing, therefore she can have many patients to test her medication on. She will have a control group and observe their swelling. Then for her treatment group she can observe if there is a difference from this group and the control group. She should study the difference in swelling between the two groups. If the swelling has gotten better in the treatment group and not in the control group, she can conclude that her medication indeed works.
