Pictorial StemLeafPlot

Stem and Leaf Plot

The stem-leaf plot is drawn in two columns separated by a vertical line. The number on the left hand side of the line represents the stem and the digit(s) on the right hand side represent(s) the leaf (leaves).

Example:

Consider the following data:

40, 42, 45, 49, 51, 54, 57, 58, 60, 63, 66, 66

Since the data is in ascending order, there is no need to sort again.

We observe that there are entries with 4, 5 and 6 in the ten’s place.

Þ 4, 5 and 6 become the stems.

Let us plot the stem and leaf as follows

4 | 0 2 5 9

5 | 1 4 7 8

6 | 0 3 6 6

• Here the leaves are from the unit’s place of the entries and the stems are from the ten’s place of the given entries.
• Repeated entries too, must be considered for plotting the leaves, as in the case of 66.
• Data should be represented in numerical order, and therefore it is best to sort the data before constructing the stem and leaf plot
