Stem-and-Leaf Plots Flashcard

Front

What is a stem-and-leaf plot?

Back

A stem-and-leaf plot is a method of displaying quantitative data in a graphical format, similar to a histogram, to retain the original data values while showing their distribution.

Front

In a stem-and-leaf plot, what does the 'stem' represent?

Back

The 'stem' represents the leading digit(s) of the data values.

Front

In a stem-and-leaf plot, what do the 'leaves' represent?

Back

The 'leaves' represent the trailing digit(s) of the data values.

Front

How do you read a stem-and-leaf plot?

Back

To read a stem-and-leaf plot, combine the stem with each leaf to form the original data values.

Front

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

Back

The purpose is to organize and display data while preserving the original values for analysis.

Front

If the stem is 3 and the leaves are 0, 1, 2, what are the data values?

Back

The data values are 30, 31, and 32.

Front

How do you determine the leaves for a given stem in a stem-and-leaf plot?

Back

Identify the data values that share the same leading digit as the stem, and use their trailing digits as leaves.

Front

What is the range of data in a stem-and-leaf plot?

Back

The range is the difference between the highest and lowest data values represented in the plot.

Front

What does it mean if a stem-and-leaf plot has more leaves on one stem than another?

Back

It indicates that there are more data values in that range compared to others.

Front

How can you find the median from a stem-and-leaf plot?

Back

To find the median, list all the data values represented in the plot and find the middle value.
