Stem and Leaf Plots

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 find the minimum value in a stem-and-leaf plot?

Back

The minimum value can be found by looking at the smallest stem and its corresponding leaf.

Front

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

Back

The maximum value can be found by looking at the largest stem and its corresponding leaf.

Front

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

Back

The purpose of a stem-and-leaf plot is to organize and display data in a way that allows for easy visualization of the distribution while preserving the original data.

Front

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

Back

Count the total number of leaves in the plot; each leaf represents one data point.

Front

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

Back

Leaves provide the actual data values and help in understanding the distribution of the data.

Front

How can you identify outliers in a stem-and-leaf plot?

Back

Outliers can be identified as leaves that are significantly distant from the other leaves in the same stem.
