The stem-and-leaf display shows the first digit (the stem) and the remaining digits (the leaves) for each value in the data set. In this case, there is one item whose stem is 4, two items whose stem is 6, one item whose stem is 7, two items whose stem is 8, and four items whose stem is 9. Therefore, there are nine items in the data set whose first digit is five.
