Front

What is the mode in a stem-and-leaf plot?

Back

The mode is the value that appears most frequently in the data set, which can be identified by looking at the leaves.

Front

How can you identify the range of data from a stem-and-leaf plot?

Back

The range can be found by subtracting the smallest leaf from the largest leaf in the plot.

Front

What type of data is best represented by a stem-and-leaf plot?

Back

Stem-and-leaf plots are best for small to moderate-sized data sets of quantitative values.

Front

Can a stem-and-leaf plot show frequency?

Back

Yes, the number of leaves for each stem can indicate the frequency of data values within that range.
