A Dot Chart or Dot Plot is a statistical chart consisting of data points plotted on a fairly simple scale, typically using filled in circles.

They are useful for highlighting clusters and gaps, as well as outliers (points that lie on the outside).

To draw a dot plot, count the number of data points falling into a certain category. Using a suitable scale, next neatly draw a stack of dots falling into that category directly on top of each another. Repeat the process for other categories.

The distribution of dots on a dot plot can also be described as ‘*even*‘, ‘*skewed to the left’* or ‘*skewed to the right*‘.

An example of a dot plot showing 100m sprint times of athletes is shown below.
