Bar Graph / Histogram

Bar Graphs have identification down one side and quantities on the other.

Histograms have quantities down one side and a range of numbers down the other.
Bar graphs can either go horizontal or vertical. The bars usually don't touch. Histogram usually go vertically and the bars do touch.

Just as with line plots or any other kind of graph, you can find the mean, medium, mode, and range by following methods previously taught.

The bars or the graph can be filled in or just lines.
A ruler should always be used to draw the lines.
