What is a Stem and Leaf Plot?
A stem and leaf plot is a way to display a set of data by grouping it into ranges, called stems, and listing the individual data points, called leaves, next to each stem. This type of plot is commonly used to visualize and analyze large datasets. In a stem and leaf plot, the stem represents the first digit or digits of the data point, and the leaf represents the last digit or digits.
Example of a Stem and Leaf Plot
The given stem and leaf plot is:
| Stem | Leaf |
|---|---|
| 1 | 1, 3 |
| 2 | 2, 6 |
How to Interpret a Stem and Leaf Plot
To interpret a stem and leaf plot, we need to understand that each stem represents a range of values, and the leaves represent the individual data points within that range. For example, in the given stem and leaf plot, the stem "1" represents the range of values from 1.0 to 1.9, and the leaves "1" and "3" represent the individual data points 1.1 and 1.3, respectively.
Matching the Stem and Leaf Plot to the Correct Set of Data
We are given a set of data points: 1.1, 1.3, 2.2, 2.6, 2.8, 3.1. We need to match the stem and leaf plot to the correct set of data. To do this, we need to group the data points into ranges, called stems, and list the individual data points, called leaves, next to each stem.
Step 1: Group the Data Points into Stems
Let's group the data points into stems:
- Stem 1: 1.1, 1.3
- Stem 2: 2.2, 2.6, 2.8
- Stem 3: 3.1
Step 2: List the Leaves Next to Each Stem
Now, let's list the leaves next to each stem:
| Stem | Leaf |
|---|---|
| 1 | 1, 3 |
| 2 | 2, 6, 8 |
| 3 | 1 |
Conclusion
Based on the given stem and leaf plot and the set of data points, we can conclude that the correct match is:
| Stem | Leaf |
|---|---|
| 1 | 1, 3 |
| 2 | 2, 6, 8 |
| 3 | 1 |
This match is based on the fact that the stem and leaf plot groups the data points into ranges, and the leaves represent the individual data points within each range.
