Q. 2.53 - Elementary Statistics

Question

Suppose that you have constructed a stem-and-leaf diagram and discover that it is only moderately useful because there are too few stems. How can you remedy the problem?

Step-by-Step Solution

Answer

According to the presented statistics, the solution to the problem of too few stems is to employ two or more lines per stem. 

Step 1: Concept introduction

A stem-and-leaf display, also known as a stem-and-leaf plot, is a tool for visualising the shape of a distribution by displaying quantitative data in a graphical fashion, similar to a histogram.

Step 2: Explanation

If the number of stems in a stem and leaf plot is insufficient, it is preferable to use two lines per stem rather than one line per stem since it produces a more usable stem and leaf diagram.

It's sometimes advantageous to utilise five lines per stem, with the first line representing the leaf digits $0$ and $1$, the second line representing $2$ and $3$, and so on, and the fifth line representing the digits $8$ and $9$ .
