What Is a Histogram?

A histogram is a graphical depiction that creates a group of data points into user-specified ranges. Similar in presentation to a bar graph, the histogram summarizes a data set into a simple interpretation visually by taking multiple data points and arranging them into logical ranges or cases.

How Histograms Work

Histograms are generally applied in statistics to show how many of a particular kind of variable happen within a specific range.

For example, a statement centered on the demography of a nation may use a histogram to show how many people are between the ages of 0 – 5, 6 – 10, 11 – 15, 16- 20, etc. This histogram would seem similar to the example given below.
