Example 1

A pharmacy records the number of customers each hour that the pharmacy is open. The staff is using the information to determine how many people need to be working at the pharmacy at each time of day. The number of customers is in the table below. Use the table to create a histogram to help the pharmacy staff understand how many customers are in the pharmacy at each time of day.
  1. Draw a number line on an x-axis that corresponds to the range of the data.
  2. Draw a y-axis that corresponds to the least and greatest number of times a data value is repeated. The y-axis should be to the left of the labeled x-axis.
  3. Create a rectangle at each value showing the number of data points at each data value.
