Example 1.11

Twenty-five households are polled in a marketing survey, and Table 1.12 lists the numbers of quarts of milk purchased during a particular week. Construct a relative frequency histogram to describe the data.

Table 1.12

0      3      5      4      3

2      1      3      1      2

1      1      2      0      1

4      3      2      2      2

2      2      2      3      4

Solution

The variable being measured is “ number of quarts of milk,” which is a discrete variable that takes on only integer values. In this case, it is simplest to choose the classes or intervals as the integer values over the range of observed values: 0, 1, 2, 3, 4, and 5.
