A histogram is a way of showing how often events happen by using rectangles. The width of a rectangle represents a class, and the height of a rectangle represents a frequency. It’s a graph of continuous data, as the width of a rectangle is along the X-axis, and the height of a rectangle is along the Y-axis.

• Histogram: A histogram is a graph that uses adjacent, continuous bars, and the areas of the bars represent the frequency of data.Bar
• Chart: A bar chart is a graph of separate bars, where each bar represents a category, and the height of a bar, not the area, represents data.
• Pictograph: A pictograph is a graph of pictures or icons, which represent data.
