Suppose you are a participant in a project to study the effectiveness of a new treatment for high cholesterol. The new treatment will be compared to a current treatment by recording the change in cholesterol readings over a 10-week treatment period. The effectiveness of the treatment may depend on each participant’s age, body fat percentage, diet, and general health. The study will involve at most 30 participants because of cost considerations.
a. Describe how you would conduct the study using independent samples.
b. Describe how you would conduct the study using paired samples.
c. How would you decide which method, paired or independent samples would be more efficient in evaluating the change in cholesterol readings?
