Goal: We want to use the histogram to describe the distribution of the variable.
-Symmetric - mirror (or almost mirror) image on each side of the middle.
-Skewed left - the distribution has observations that form a tail on the left hand side of the distribution.
-Skewed right - the distribution has observations that form a tail on the right hand side of the distribution.
- Unimodal – has only one largest class
- Bimodal – has two distinct largest classes
-No distinct Shape
