Let’s solve each stem-and-leaf plot problem step by step.
We’ll go one at a time, sorting the data and placing it correctly in the stem-and-leaf format. Remember:
→ The “stem” is the first digit(s) of the number.
→ The “leaf” is the last digit.
→ Leaves should be listed in order from smallest to largest for each stem.
→ The key tells you how to read the plot (e.g., 3|7 = 37).

Problem 1: Data: 26, 37, 48, 33, 49, 26, 19, 26, 48
Step 1: Sort the numbers:
19, 26, 26, 26, 33, 37, 48, 48, 49
Step 2: Break into stems and leaves:
- Stem 1 → leaf 9 → 19
- Stem 2 → leaves 6, 6, 6 → 26, 26, 26
- Stem 3 → leaves 3, 7 → 33, 37
- Stem 4 → leaves 8, 8, 9 → 48, 48, 49
So the plot is correct as shown. Key: 3|7 = 37 ✔️

Problem 2: Data: 67, 42, 58, 41, 54, 65, 65, 54, 69, 53
Sort: 41, 42, 53, 54, 54, 58, 65, 65, 67, 69
Stems:
- Stem 4 → 1, 2 → 41, 42
- Stem 5 → 3, 4, 4, 8 → 53, 54, 54, 58
- Stem 6 → 5, 5, 7, 9 → 65, 65, 67, 69
Plot matches. Key: 6|5 = 65 ✔️

Problem 3: Data: 552, 547, 578, 543, 559, 565, 544, 552
Sort: 543, 544, 547, 552, 552, 559, 565, 578
Here, since all numbers are 3-digit, we use the first two digits as stem, last digit as leaf.
Stem 54 → leaves 3, 4, 7 → 543, 544, 547
Stem 55 → leaves 2, 2, 9 → 552, 552, 559
Stem 56 → leaf 5 → 565
Stem 57 → leaf 8 → 578
Plot matches. Key: 55|9 = 559 ✔️
---
Problem 4: Data: 5.8, 6.4, 5.8, 7.5, 6.9, 8.4, 7.6, 6.4, 8.7
These are decimals. We treat the whole number part as stem, decimal digit as leaf.
Sort: 5.8, 5.8, 6.4, 6.4, 6.9, 7.5, 7.6, 8.4, 8.7
Stem 5 → leaves 8, 8 → 5.8, 5.8
Stem 6 → leaves 4, 4, 9 → 6.4, 6.4, 6.9
Stem 7 → leaves 5, 6 → 7.5, 7.6
Stem 8 → leaves 4, 7 → 8.4, 8.7
Plot matches. Key: 8|4 = 8.4 ✔️
---
Problem 5: Data: 74, 88, 97, 72, 79, 86, 95, 79, 83, 91
Sort: 72, 74, 79, 79, 83, 86, 88, 91, 95, 97
Stem 7 → leaves 2, 4, 9, 9 → 72, 74, 79, 79
Stem 8 → leaves 3, 6, 8 → 83, 86, 88
Stem 9 → leaves 1, 5, 7 → 91, 95, 97
Plot matches. Key: 8|6 = 86 ✔️
---
Problem 6: Data: 258, 267, 256, 275, 269, 256, 269, 256
Sort: 256, 256, 256, 258, 267, 269, 269, 275
Use first two digits as stem, last digit as leaf.
Stem 25 → leaves 6, 6, 6, 8 → 256, 256, 256, 258
Stem 26 → leaves 7, 9, 9 → 267, 269, 269
Stem 27 → leaf 5 → 275
Plot matches. Key: 26|9 = 269 ✔️

All plots are already correctly filled out in the answer key. Since this is an answer key sheet, and all answers are provided and verified correct, there’s no new calculation needed — but if you were doing this yourself, you’d follow the steps above.
Final Answer: All stem-and-leaf plots are correctly completed as shown in the image.
Parent Tip: Review the logic above to help your child master the concept of stem leaf plot worksheet.
