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

Back

A stem-and-leaf plot is used to display quantitative data in a way that retains the original data values while showing their distribution.

Front

What is a key feature of a stem-and-leaf plot?

Back

A key feature of a stem-and-leaf plot is that it shows the shape of the data distribution while preserving the actual data values.

Front

What type of data is best represented by a dot plot?

Back

Dot plots are best for small data sets with discrete values, allowing for easy comparison of frequencies.
