The histogram is used to summarize discrete or continuous data that are measured on an interval scale. It is often used to illustrate the major features of the distribution of the data in a convenient form. A histogram divides up the range of possible values in a data set into classes or groups. Histograms such as the one above are very easy to interpret. They are a form of a bar graph.
