What is a stem and leaf plot? How is it used and how exactly do i solve one? (an example would be great)

Answer 1

A stem and leaf plot is a table where each of the data is divided into two parts. The stem, that is the first digit and the leaf is the last digits. Let's say that we have the following set of data.

$10,\text{ 12, 25, 28, 29, 35, 38, 40, 44}$

If we want to make a stem and leaf plot of that data, we first write a column where we place the first digit of each number without repetition, like this:

$\begin{gathered} 1 \\ 2 \\ 3 \\ 4 \end{gathered}$

These are the stems. Now the leaves are the last digit of each number put in order next to the corresponding first digit, like this:

$\begin{gathered} 1\parallel\text{ 0 2} \\ 2\parallel\text{ 5 8 9} \\ 3\text{ }\parallel\text{5 8} \\ 4\text{ }\parallel\text{0 4} \end{gathered}$
