A histogram. A histogram has a horizontal axis labeled Values from negative 2 to 10 in increments of 2 and a vertical axis labeled Frequency from 0 to 300 in increments of 50. The histogram has vertical bars of width 30, starting at the horizontal axis value of negative 1.5. The approximate heights of the bars are as follows, where the horizontal axis label is listed first and the approximate height is listed second: negative 1.5, 30; 0.5, 125; 1.5, 230; 2.5, 250; 3.5, 160; 4.5, 130; 5.5, 45; 6.5, 20; 7.5, 5. All values are approximate. A histogram
