Once you have the center and range of your data, you can begin to describe its shape. The skew of a dataset is a description of the data’s symmetry.

A dataset with one prominent peak, and similar tails to the left and right is called symmetric. The median and mean of a symmetric dataset are similar.

A histogram with a tail that extends to the right is called a right-skewed dataset. The median of this dataset is less than the mean.

A histogram with one prominent peak to the right, and a tail that extends to the left is called a left-skewed dataset. The median of this dataset is greater than the mean.

### Instructions

**1.**

Replace the question marks in `?????????-skew`

with `left`

, `right`

, or `no`

.

`no`

in this circumstance represents a symmetric dataset.

**2.**

Replace the question marks in `average is ?????????? than the median`

with `greater`

or `less`

.
