Histograms As A Tool To Describe Data

Make a Histogram


Make a Histogram

A histogram is a graph that shows data in intervals of equal size.

As a class, make a histogram for the data in the “How Long Can Sixth Grade Students Swim Under Water?” line plot. Use these steps:

  • Decide on a range for each bin. This range is called the bin width, and it should be the same for each bin.
  • Determine the number of data points in each bin.
  • Draw a horizontal and vertical axis.
  • Look at the highest number of data points in your bins, and use that number to determine your scale for the vertical axis.
  • Divide the horizontal line into intervals based on your data and bin width.
  • Label the vertical and horizontal lines and create a title for your histogram.
