Histogram






http://erc.msh.org/quality/example/exampl18.cfm

A histogram is a graphical representation of the frequency of occurrences of a certain data set. Each bar represents an amount of times a particular variable occurred. In this histogram, the waiting time during some registration is what was being measured. As you can see, waiting anywhere from 61-90 minutes was the most common time of wait during registration.  Waiting 91-120 minutes happened the least with only two occurrences.
