## Online Tutoring Is The Easiest, Most Cost-Effective Way For Students To Get The Help They Need Whenever They Need It.

This is a plot which is represented by splitting a number into stem and leaf where stem will be on left and leaf is on the right place, generally stem and leaf shows the place value.

For an example we can split 93 as 9 as a stem and 3 as a leaf.

Example: - The following data represent the costs (in dollars) of a sample of 20 postal mailing by a company.

2.75    5.47    4.65    3.32    2.09
1.83    1.93    2.78    3.34    3.20
3.21    4.95    5.42    4.84    4.10
3.45    5.11    1.97    2.84    4.15

Using dollars as a stem and cents as a leaf construct a stem and leaf plot of the data.

Solution: -

Stem   Leaf

1          |           83        93        97
2          |           09        75        78        84
3          |           20        21        32        34        45
4          |           10        15        65        84        95
5          |           11        42        47

Another example could be: - The following data are monthly rents paid by a sample of 20 households selected from a small city.

880     1081   1075   1023   775
965     960     985     932     850
825     915     1191   1035   1151
1175   952     1140   750     1140

Solution: - Each value in the data set contains either three or four digits. We will take the first digit for three-digit numbers and first two digits of four-digit numbers as stem.

Stem   Leaf

7          |           75        50
8          |           80        25        50
9          |           32        52        15        60        85        65
10        |           23        81        35        75
11        |           91        51        40        75        40
