A Histogram is a graph created by Karl Pearson, which is used to show a distribution of data. It uses adjacent rectangles to show the frequencies of a certain occurrence compared to some other piece of information. The height of each rectangle in a histogram represents the frequency of occurrence. The total area of a histogram is equal to the number of data observed.
The graph shown displays the distribution of grades of students in a certain class. The majority of students (about 40) received a grade lying somewhere between 60% and 80%. Approximately 3-4 students received a grade somewhere between a 0 or a 20% out of a possible 100%.
