Line & Stem-and-Leaf Plots

Front

What is a line plot?

Back

A line plot is a graph that shows data along a number line, where each data point is represented by an 'X' or a dot above the corresponding value.

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.

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 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?

Back

A line plot is used to display the frequency of data points along a number line, making it easy to see trends and patterns.

Front

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.
