Key Concepts
Property A stem and leaf plot is a data display that uses some digits as 'stems' and others as 'leaves.' The 'stems' have a greater place value than the 'leaves.'.
Examples For ages {41, 10, 56, 32, 41, 17, 41}, the value 41 appears most often. For data set {23, 25, 31, 31, 40}, the stem for '3' has leaves '1, 1'. The key tells you how to read it: $4|1$ represents the number 41.
Explanation This plot is a neat way to organize numbers, like sorting trading cards by their first digit. The 'stem' is the main group (like the tens place), and the 'leaves' are all the individual values branching off. It keeps data tidy and easily shows the mode!
