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, that helps to visualize the shape of a distribution.

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

Back

In a stem-and-leaf plot, the 'stem' represents the leading digit(s) of the data values, while the 'leaf' represents the last digit. For example, in '3 | 4', '3' is the stem and '4' is the leaf, representing the number 34.

Back

The leaf represents the last digit of the data values.

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 purpose of using a line plot?

How do you create a stem-and-leaf plot from a list of numbers?

Back

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

Front

What is the advantage of using a stem-and-leaf plot over a histogram?

Back

A stem-and-leaf plot retains the original data values, allowing for easier identification of individual data points, while a histogram only shows frequency.

Front

What is the first step in interpreting a line plot?

Back

Identify the values represented on the number line and the frequency of each value.
