You are examining the data with a split stem-and-leaf plot. Here is the start of the plot:
5 | 558
6 | 0001223

What should be entered in the second to last row of this table?

In a split stem-and-leaf plot, each stem is divided into two parts. The first part of each stem contains leaves from 0-4, and the second part contains leaves from 5-9. The row corresponding to the second part of the stem "7" (for values from 75 to 79) needs to be completed. Let's go through the data and extract the relevant values.

### Data:
71, 69, 62, 66, 71, 55, 63, 62, 75, 72, 61, 65, 60, 58, 66, 79, 71, 60, 55, 60

Values in the 70s range:
- 71, 71, 71, 72, 75, 79

In the first part of the stem "7" (for 70-74), the leaves would be: 1, 1, 1, 2 (these are already in the plot).

Now, for the second part of the stem "7" (for 75-79), the leaves would be: **5, 9**.

Thus, the second to last row should be:

**7 | 59**

This completes the split stem-and-leaf plot for the 70s.

Here are 5 related questions to extend your understanding:
1. How is a split stem-and-leaf plot different from a regular stem-and-leaf plot?
2. Why might you use a split stem-and-leaf plot rather than a regular one?
3. What are the advantages of using stem-and-leaf plots for data visualization?
4. How can you quickly identify the median value using a stem-and-leaf plot?
5. How do you handle data with decimal points in a stem-and-leaf plot?

**Tip:** Always remember that stem-and-leaf plots are most useful for small to moderately sized data sets. For very large data sets, other visualizations like histograms may be more appropriate.

Learn how to complete a split stem-and-leaf plot with the given data set: 71, 69, 62, 66, 71, 55, 63, 62, 75, 72, 61, 65, 60, 58, 66, 79, 71, 60, 55, 60. This detailed explanation covers data visualization techniques, focusing on how to correctly split the stems for better clarity. Suitable for students in Grades 7-9.
