Is a histogram a mathematical model?
In math, a histogram is a visual way to display frequency data using bars. A feature of histograms is that they show the frequency of continuous data, such as the number of trees at various heights from 3 feet to 8 feet. For example, the height of the trees can be grouped into 3 to 4 feet, 5 to 6 feet, and 7 to 8 feet.

What does a histogram in maths look like?
A histogram looks like a bar chart , except the area of the bar, and not the height, shows the frequency of the data . The area of the bar represents the frequency, so to find the height of the bar, divide frequency by the class width. This is called frequency density.
