Etymology

Origin of histogram

First recorded in 1890–95; histo- + -gram 1

Explanation

Histogram is a fancy word for "bar graph." If you use the word histogram to describe a chart that uses bars or rectangles to display how often something happens, your math teacher will be impressed. The benefit of a histogram is that instead of a list of numbers, you can see information graphed on a bar chart, which makes it much more easy to understand. The word comes from the Greek root histos which means both "the mast of a ship" and "anything set upright," like the bars on a histogram.
