StemandLeaf Plots
Key Questions

Answer:
Look below.
Explanation:
A stemandleafplot is a table where each data value is split into two parts, one called the stem and the other the leaf. The stem is the first digit/digits, and the leaf is the last digit/digits.:

Stemandleaf plots are a method for showing the frequency with which certain classes of values occur. You could make a frequency distribution table or a histogram for the values, or you can use a stemandleaf plot and let the numbers themselves to show pretty much the same information.

In short, these are the steps:
1) Reorder your data set from lowest to highest (use the Data Sort command in your spreadsheet software).
2) Look at the minimum and maximum data points and determine the data range.
3) Split the data range into a convenient number of equal intervals (for example, a data range of 48 can be split into 6 intervals with an interval step of 8 or into 8 intervals with an interval step of 6).
4) Build a frequency table for the intervals defined at step 3. (Count the frequencies, i.e. the number of data points within each interval and write them in a table).
5) Create a column chart having the data intervals on the xaxis and the frequencies on the yaxis. (Use the provided command in your spreadsheet software).
For a practical example, have a look at this Google Sheet document that contains three sheets (raw data set, ordered data set and frequency table with histogram).
