Stem & Leaf Plots

Stem & Leaf Plots

A stem – and – leaf plot is another method for organizing data. Each number in the data is broken up into a “stem” and a “leaf”. The “leaf” IS ALWAYS the last digit in the number ( the ones place ). The “stem” IS ALWAYS the numbers preceding the last digit ( no matter how many are there ).

To create the data list, just put each “leaf” behind the “stem” to the left of the vertical line…

Stem & Leaf Plots

To create a stem and leaf plot from a list of data, we first must get the data in ascending order ( small to big ).

To create a stem and leaf plot from a list of data, we first must get the data in ascending order ( small to big ).

EXAMPLE # 2 : Create a stem – and – leaf plot from the following test scores.

77 , 83 , 71 , 66 , 97 , 77 , 86 , 62 , 75 , 93 , 87

Now identify all the “stems”. All numbers that appear IN FRONT of the last digit.
