Which one will be the best design of the units of stem and leaf for a stem-and-leaf display?

a. 10's for stem unit and 1's for leaf unit
b. 100's for stem unit and 10's for leaf unit
c. 1's for stem unit and 0.1's for leaf unit
d. 1000's for stem unit and 100's for leaf unit

Answer 1

1000's for stem unit and 100's for leaf unit

Explanation:

The best design of the units of stem and leaf for a stem-and-leaf display given the set of sample data is: use 1000's for stem unit and 100's for leaf unit. All the numbers in the sample data are 1000's with two decimal places. The idea is for the stem to display the 1000's while the decimal places are displayed by the leaf.
