B 2: Explanations of Central Tendency Measures
Assume youre doing research on diets. Youve run a study that compares the effectiveness of two diet plans. The mean weight loss for both distributions is identical, meaning they have the same mean.

What does the dispersion of scores imply about weight loss on the two diets?
