Histograms display information through an x-axis and a y-axis. One line has an independent variable and the other has a dependent variable. The histogram above has the dependent variable (the number of students getting a particular grade) on the vertical axis and the independent variable (the actual grade) on the horizontal axis. According to this histogram most students scored between 60% and 80 % and the least amount of students scored from 0% to 20%.
