If you have a Facebook account, you are allowed to have up to {eq}5,000 {/eq} friends. At that point, Facebook cuts you off, and you have to "unfriend" people to add more. Imagine you collected data from Facebook users at your university about the number of friends each has:

a. What type of skew might you expect for such data?

b. Do the skewed data represent a floor effect or ceiling effect?

## Skewness

In Statistics, we can graph the distribution of a dataset to determine if the data is skewed. If outliers lie on the left hand side of the data set, then the data is likely to be skewed to the left. Similarly if outliers lie on the right hand side of the data set, then the data is likely to be skewed to the right.
