Stem-and-Leaf Plot

Morning friends, have you had a chance to go outside today? Have you seen any living flowers  lately? I hope so, I personally consider nature to be my church. I feel most alive and at peace when I'm engulfed in it.

My Blog for today is about stem-and-leaf plots. When I hear stem-and-leaf I think of flowers. Stem-and-leaf plots are valuable tools when quickly organizing and analyzing data. They are wonderful visual tools. They are particularly valuable when looking at line plots and histograms (graphs with intervals that are easier to read and analyze with specific numbers).

An example of a stem-and-leaf plot is below:

1     1 1 2 5 8 9
2     0 1 2 2 4 7
3     4 8 9 9
4     1 2 3 7 9

The numbers on the left (1, 2, 3, and 4) represent the tens place. The numbers on the right represent the ones place and represents how many are in that category. For instance, the 1's have six numbers: 11, 11, 12, 15, 18, 19.

You can introduce stem-and-leaf plots as early as third grade probably.

Carpe diem,
Cass
