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

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

Back

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

Front

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

Back

The maximum value is 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 data to make it easier to see the distribution and identify patterns.

Front

How can 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 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.

Front

How do you create a stem-and-leaf plot from a data set?

Back

1. Separate each number into a stem and a leaf. 2. List the stems in a vertical column. 3. Write the leaves next to their corresponding stems.

Front

What does it mean if a stem-and-leaf plot is skewed to the right?

Back

If a stem-and-leaf plot is skewed to the right, it means that there are more lower values and fewer higher values.
