Explanation:

Step1: Identify data range

The data ranges from 51.2 to 79.1. When using split - stems, we consider the tens digit as the stem and the units and tenths digits as the leaves.

Step2: Determine stems

The possible tens - digit values are 5, 6, 7. For each of these values, we will have two split - stems (e.g., for 5, we have 5 | 0 - 4 and 5 | 5 - 9). So the stems will be 50 - 54, 55 - 59, 60 - 64, 65 - 69, 70 - 74, 75 - 79.
