4.3 Bar Chart
A bar chart can also be used when observations aren’t only numbers.  There are two types of bar charts; ones with vertical bars and horizontal bars.

A survey was done in a class about favorite sports.

The results were recorded in a frequency table.

The diagram can looks like this vertical bar chart.

or it can look like this horizontal bar chart.

One good thing, to think about is that the bars should always be equally wide and that the diagram becomes more clear if you use different colours.
