Question

How would you draw a stem and leaf display with decimals such as 18.8 and 20.3?

Answer 1

To draw the stem and leaf diagram for decimal like 18.8, 20.3 etc we need to take stems like 18, 20. Leaf for stem 18 will be 8 and leaf for stem 20 will be 3.

Following is the example data:

Data
18.8
20.3
20.6
20.1
18.5
18.6
19.5
19.6
19.7
22.5
22.6
22.4
25.6
25
25.1

Following is the stem and leaf display of above data:

Stem and Leaf plot for Data stem unit = 1 leaf unit = 0.1 Frequency Stem Leaf 18' 568 19' 567 20' 136 GwOowowww 22' 456 25 016

In stem-and-leaf plot, 20 | 1 means 20 + (1*0.1) = 20.1.
