Stem-and-Leaf Plots
Stem-and-Leaf Plots is a skill on Pengi from Lesson 1: Stem-and-Leaf Plots in Big Ideas Math, Advanced 1.
Key Concepts
A stem and leaf plot is a way to organize numerical data that shows both the shape of the data distribution and the actual data values. To create a stem and leaf plot, split each data value into two parts: the "stem" (usually the tens digit or higher place values) and the "leaf" (usually the ones digit). List the stems vertically in order, then write the corresponding leaves horizontally next to each stem. This type of graph allows us to identify clusters (data points together in a group), gaps (intervals without any reported values), peaks (stems where there are more leaves than for nearby stems), and outliers (values that are significantly different from the rest of the data).
