  • Unlike with line plots, measures of center and spread cannot be found by looking at a histogram, because individual data values are not shown. The number of data points in a histogram can be found by adding the frequencies of the bins.
  • To make a histogram, you have to choose a bin width. You can choose a bin width based on where the data are distributed (so that the shape of the data is clear), or to organize the data in a logical way (such as by 10s or 5s).

Hint:

Can you:

  • Explain what a histogram is?
