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 help visualize the shape of a distribution. Each number is split into a 'stem' (the leading digit) and a 'leaf' (the trailing digit).

Front

How do you find the maximum value in a stem and leaf plot?

Back

To find the maximum value, look at the largest stem and the largest leaf associated with it.

What does the 'leaf' represent in a stem and leaf plot?

Back

The 'leaf' represents the trailing digits of the data values.

Front

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

Back

The range can be determined by subtracting the minimum value from the maximum value.

Front

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

Back

The purpose is to organize data in a way that retains the original values while allowing for easy visualization and analysis.

Front

How do you count the number of data points in a stem and leaf plot?

Back

Count each leaf in the plot; each leaf represents one data point.

Front

What is the difference between a stem and leaf plot and a histogram?

Back

A stem and leaf plot retains the original data values, while a histogram groups data into ranges.

How can you identify clusters in a stem and leaf plot?

Back

Clusters can be identified by looking for groups of leaves that are close together on the same stem.
