What do the leaves on the stem-and-leaf plot represent?
The leaves on a stem-and-leaf plot represent the units digit(s) of the data values. They provide a way to organize and display the individual data points in a data set. The stems represent the tens digits of the data values, while the leaves represent the units digits.
To create a stem-and-leaf plot, you need to follow these steps:
1. Arrange the data values in ascending order.
2. Identify the minimum and maximum values in the data set.
3. Split each data value into a stem and a leaf. The stem is formed by the remaining digits except for the units digit, while the leaf consists of the units digit(s) of the data value.
4. Write the stems in a vertical column from smallest to largest, leaving enough space for the corresponding leaves beside them.
5. Write each leaf beside its respective stem, aligned vertically.
6. Create a key or legend to explain the values of the stems and leaves.
By using a stem-and-leaf plot, you can quickly identify the distribution and frequency of the data values, as well as identify any outliers or patterns in the data set.
