How Do You Create A Histogram Graph?
A histogram is a type of graph that shows how often different events occur. Histograms are particularly useful for show distributions, such as grades on a test or the heights of a group of people, because they simplify the information into an easier to understand format than the raw data. Determine the ranges of each data bin. If you have a number set like {1,1,1,2,2,3,3,3,4,4,5,5,5}, each number can have its own data bin. However, if your data covers a wider range like {2, 4, 7, 11, 14, 18, 19, 23, 25, 31, 33, 34, 41}, you should consider having each data bin represent a range such as 1-10, 11-20, 21-30, 31-40, and 41-50. Determine how many occurrences, or frequency, there are for each data bin. For example, in the second data set above, there are three numbers 1-10, four numbers 11-20, two numbers 21-30, three numbers 31-40, and one number 41-50. Create the graph. Use the data bins on the x-axis and the frequency on the y-axis. The first bar would be 1-10 and would go up three becaus
