A histogram is a graphical representation of a frequency distribution using bars of equal width, without gaps between them, where the area of each bar corresponds to the frequency of observations in the corresponding interval. The document provides instructions on how to draw a histogram by marking class intervals on the x-axis, frequencies on the y-axis, and plotting corresponding values to draw bars for each interval. It includes an example of constructing a histogram from a frequency table of student marks.
