Question

select all the distribution shapes for which it is most often appropriate to use the mean. a bell - shaped b bimodal c skewed d symmetric e uniform

Explanation:

The mean is a good measure of central - tendency for symmetric distributions. Bell - shaped distributions are symmetric. Uniform distributions are also symmetric in a sense. In skewed distributions, the mean can be pulled by extreme values. Bimodal distributions may have two distinct centers and the mean may not represent the data well.

Answer:

A. bell - shaped, D. symmetric, E. uniform
