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.

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

Back

The 'stem' represents the leading digit(s) of the data values.

Front

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

Back

The 'leaf' represents the trailing digit(s) of the data values.

Front

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

Back

1. Organize the data in ascending order. 2. Identify the stems (leading digits). 3. Write the stems in a vertical column. 4. Write the leaves (trailing digits) next to their corresponding stems.

Front

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

Back

The purpose is to visualize the distribution of data while preserving the actual data values.

Front

How can you find the median using a stem-and-leaf plot?

Back

To find the median, arrange the data in order and locate the middle value. If there is an even number of values, average the two middle values.

Front

What is the mode in a data set?

Back

The mode is the value that appears most frequently in a data set.

Front

How can you identify the mode using a stem-and-leaf plot?

Back

The mode can be identified by looking for the stem with the most leaves.

Front

What is the range of a data set?

Back

The range is the difference between the highest and lowest values in the data set.

Front

How do you calculate the range from a stem-and-leaf plot?

Back

To calculate the range, subtract the smallest leaf value from the largest leaf value.
