A histogram is a graphical representation of a grouped frequency distribution with continuous classes. Bell-shaped: A bell-shaped picture, shown below, usually presents a normal distribution. The above distribution resembles a normal distribution with the tails being cut off. The probabilities of each outcome are the heights of the bars of the histogram. Begin by marking the class intervals on the X-axis and frequencies on the Y-axis. If not, discuss the reasons behind the differences and see if you can reach agreement. Every bar on the image histogram represents one intensity level. (There were 5 people who earned 0 or 1 tickets and 13 people who earned 6 or 7 tickets.).
