If a student got a 75 which bar should increase.
Histogram A histogram is a type of chart used to represent the distribution of a set of data. The X-axis are intervals that show the scale of values which the measurements fall under. It can be defined as a set of rectangles with bases along with the intervals between class boundaries and with areas proportional to frequencies in the corresponding classes. A statistical graph that represents the frequency of values of a quantity by vertical rectangles of varying heights and widths.
