Stem-and-leaf plot
Learn stem-and-leaf plot in Grade 9 math — This makes it super easy to see how your numbers are spread out, like finding clusters or gaps in test scores!
Key Concepts
Property A data display that uses some digits as "stems" and others as "leaves." The "stems" have a greater place value than the "leaves.".
Explanation Think of it as sorting data by its first digits (the stem) and listing the last digits (the leaves) next to it. This makes it super easy to see how your numbers are spread out, like finding clusters or gaps in test scores! It is a fantastic way to organize data while keeping all the original values visible.
Examples Dataset: 23, 41, 28, 35, 41. Plot: 2|3, 8, 3|5, 4|1, 1. Key: 2|3 = 23. Test scores: 85, 92, 81, 85, 78. Plot: 7|8, 8|1, 5, 5, 9|2. Key: 8|1 = 81. Temperatures: 53, 55, 64, 69. Plot: 5|3, 5, 6|4, 9. Key: 5|3 = 53 degrees.
