Stem and Leaf plot- A kind of graph used to represent number data
horizontally
Statistics- Number data; information from numbers
Stem and leaf plots are graphs that show statistics in a different way
than the other graphs you commonly see. They are not really used
and sometimes can be confusing at start. So a short cut to making
these graphs is copying down the numbers at the side or on a
different piece of paper. After that, you could make and complete
the graph.
You read a stem and leaf plot by looking at the number to the left to
one of the numbers to the right. Add the number to the right behind
the number to the left. This number is a part of your statistics.
Here is an example:
1. A plot on a stem and leaf plot reads: (left) 4, (right) 0,9,8,7,3, and
4. So, the data is 40, 49, 48, 47, 43, 44
Here are some real world examples:
1. I suggest using these to keep track of your scores.
2. Some college students might use this to keep track of their scores
and other stuff.
Make a stem and leaf plot for each data set:
Sample 1: 30,69,45,56,76
1) 62,54,64,30,90,89,99,20,56,56
2) 12,24,36,48,60,72,84,96,108
3) 14,28,42,56,70,84,98
4) 11,12,13,14,21,22,23,24,31
