How To Draw Stem And Leaf Chart With Three Digit Numbers
Stem and foliage plot
A stem and leaf plot organizes data by showing the items in order using stems and leafs.The leafage is the last digit on the right or the ones digit.The stem is the remaining digit or digits.
Hither is how to easily pull out the stem and the leaf:
For 12, 2 is the leaf and 1 is the stem. For 45.7, seven is the leafage and 45 is the stem.
Basically, as you tin can see in the figure below, a straight vertical line is used. Then, we put all stems on the left and all leaves on the right.
How to construct a stalk and leaf plot
We will now illustrate with three carefully chosen examples.
Example #i:
24, x, 13, two, 28, 34, 65, 67, 55, 34, 25, 59, 8, 39, 61
Showtime, put this data in order
2, vi, 10, 13, 24, 25, 28, 34, 34, 39, 55, 59, 61, 65, 67
Nosotros will employ 0, 1, 2, 3, four, 5, and half-dozen as stems. The plot is displayed beneath:
A stem and leaf plot tin help you quickly place how frequently data occur. For instance, a quick wait at the effigy in a higher place volition show that the number 34 occurs most oftentimes. Information technology can besides help you identify rapidly the least and the greatest data value.
Example #2:
This time, the information is already in club
104, 107, 112, 115, 115, 116, 123, 130, 134, 145, 147
We will use 10, 11, 12, 13, and 14 equally stems. The plot is displayed below:
Sometimes, information technology is useful to testify leafs on both sides of the stem. Say for instance you teach algebra in two dissimilar classes.
You may in this instance want to compare performance for the classes to see which grade performed better.
Example #iii:
Grade for course A: threescore, 68, 70, 75, 84, 86, 90, 91, 92, 94, 94, 96, 100, 100
Grade for class B: 60, 60, 70, 71, 73, 73, 75, 76, 77, 84, 85, 86, 91, 92
The plot is displayed below:
A quick look at the graph and you will meet that course A performed a lot better than class B.
Class B has more scores in the 70s than class A.
Course A has more scores in the 90s than class B.
This is one of the good features of stalk and leaf plots. It helps you to quickly wait at the graph and examine the data to brand sound conclusion.
