A histogram is a graph that has vertical bars indicating the frequency, rate, or percentage of different categories or points along a continuous variable. By convention, the frequency is placed along the vertical edge of the graph, and the category is placed along the horizontal line at the bottom. You can use a histogram with either quantitative or qualitative data. The basic idea is to show how a variable is distributed among different categories. The mode of a histogram is the most frequently occurring score. A distribution of scores with two such high points is referred to as bimodal.
