Question

Select all the distribution shapes for which it is most often appropriate to use the mean.

Group of answer choices

bell-shaped

bimodal

skewed

symmetric

uniform

Answer 1

Skewed

Explanation:

Looking at the options;

- Bimodal has to do with 2 modes in a symmetrical Distribution. Thus is doesn't apply to the mean.

-bell shaped deals with the graphical depiction of a normal probability distribution, whereby the underlying standard deviations from the mean will create the curved bell shape. So it is not used for mean.

- symmetric deals mirror images of the distribution when a vertical line is drawn down the middle of the distribution.

-skewed shape tells us whether the mean is pulled to the tail and if it is more than or less than the median.

- uniform shape means same frequency for each class.
