Introduction to stem and leaf plot

We are having lot of methods to show the data’s.  We can use the graphs, charts and tables for showing the data. Stem and leaf plot is one of the method which is used for showing large amount of data. It is like the histogram. The main difference between stem and leaf plot and histogram is we can understand the mean, mode and median from this. We will see some examples for back to back stem and leaf plot.

Terms for back to back Stem and Leaf Plot:

If we are having large number of data we will use the back to back stem and leaf plot. Just like the series of data’s. Normally a series mean it will contain more number of data’s. We can analyze the data’s using the back to back stem and leaf plot. In this we have to identify the data’s using its place value. Here the largest place value is known as stem and the other values are leaf. We already know about end to end connection method. Back to back stem and leaf method is like that only. In this we will write the leaves in both side of the stem. In the left side of the stem we are having the rounded leaves and right side we are having the truncated leaves.

Sample Problem for back to back Stem and Leaf Plot:

Back to Back Stem and Leaf Plot problem 1:

First we will see how to make a stem plot for a value consider the value 89

Solution:

Stem     is 8 and the leaf is 9.

Likewise we have to construct the back to back stem and leaf

Here we will see how to make a back to back stem and leaf plot

Let us consider a value 149.

So for this value the rounded leaf is 15 and the truncated leaf 14

Here the stem is 1

So the Back to Back Stem and leaf plot is

Rounded leaf (left)                       Stem                    Truncated leaf (right)

15                                               1                                         14

Back to Back Stem and Leaf Plot problem 2:

Draw the back to back stem and leaf plot for the following data's: 159, 260, 398, 401, 931

Solution:

Let us take the above set in ascending order. 159, 260, 398, 401, 931.

The back to back stem and leaf plot will be like the following


Rounded leaf stem Truncated leaf
16 1 15
26 2 26
40 3 39
40 4 40
93 9
93
