What is the main purpose of a stem-and-leaf plot?

• To show data in a bar graph

• Stem is the last digit, leaf is the first two digits

What is the very first step Mr. J takes when creating a stem-and-leaf plot from a given set of data?

• Draw the T-chart

• Create the key

• Order the data from least to greatest

• Determine the stems and leaves

Why is it important to order the data from least to greatest before creating a stem-and-leaf plot?

Fill in the blank: After ordering the data, the next step is to determine the stems, which are the (a)   digits of each number in a 3-digit dataset.

When adding leaves to the stem-and-leaf plot, if a number like 125 appears multiple times in the data set, how should you record its leaf?

• Only record the leaf '5' once for stem '12'

• Record the leaf '5' each time it appears for stem '12'

• Ignore repeated leaves

• Record the leaf '125' once

What is the purpose of the "key" in a stem-and-leaf plot, such as "10 | 2 = 102"?
