How to Create a Histogram
1
Build a Frequency Table
Divide your data into equally spaced intervals and count how many data points fall into each one.
2
Add Titles and Labels
Name your histogram according to the data. Label the horizontal axis with intervals and vertical axis with frequency.
3
Plot the Histogram
Draw bars above each interval on the X-axis to represent the frequency of data points in that interval.
