#### Skew:

-skew happens in the tail of a distribution

-when viewing a curve, this means skew occurs on the left or the right

-right skew occurs when a distribution has a right tail much larger than the left**Example of right skew:**

-left skew occurs when a distribution has a left tail much larger than the right**Example of left skew**

#### Peaks in data:

-distributions can have several peaks

-these peaks occur when growths of the curve are followed by recessions

-distributions that have a single peak are called unimodal**Example of unimodal distribution:**

-distributions with two peaks are called bimodal

-distributions with more than two peaks can be referred to as polymodal or (numerical prefix)modal depending on the number of peaks
