Stem and Leaf

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.

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

Back

To create a stem-and-leaf plot, separate each data point into a 'stem' (the leading digit or digits) and a 'leaf' (the trailing digit). List the stems in a vertical column and write the leaves next to their corresponding stems.

Front

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

Back

The 'stem' represents the leading digits of the data values.

Front

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 smallest leaf from the largest leaf in the plot, considering the corresponding stems.

Front

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

Back

The purpose is to organize and visualize data while preserving the original values, making it easier to identify patterns, trends, and outliers.

Front

How do you interpret the data in a stem-and-leaf plot?

Back

To interpret the data, read the stems and their corresponding leaves to understand the distribution and frequency of the data values.

Front

What is the significance of the number of leaves in a stem-and-leaf plot?

Back

The number of leaves indicates the frequency of data points for each stem, helping to visualize how many values fall within each range.

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, then locate the middle value (or average the two middle values if there is an even number of data points).

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 bins and does not show individual data points.
