A histogram has a horizontal axis labeled "Vision in Right Eye" from 0 to greater than 200 in increments of 25 and a vertical axis labeled Frequency from 0 to 50 in increments of 10. The histogram contains vertical bars of width 25, where each vertical bar is centered over a horizontal axis tick mark. The heights of the three vertical bars are as follows, where the horizontal axis value is listed first and the height is listed second: 25, 37; 50, 14; 200, 1.
