Histogram


A histogram is represented by a bar graph and can display one or more variables on a graph, these graphs are also known as frequency distribution graphs. These types of graphs shows the distribution of continuous data which is represented on an x and y axis, also the bars should always be next to each other when displaying the information. In the histogram above a single variable is represented, the scores on the final exam and the y axis represents the number of students which ranges from 0-50 and the x axis represents the score on final exam which ranges from 0-100. This graph also uses different colors to represent the different scores which I found made it easier to read.
