Unit 10 Assessment - Line Plots and Stem-and-Leaf Plots

Front

What is a line plot?

Back

A line plot is a graph that shows the frequency of data along a number line, using X's or other symbols to represent each data point.

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, where each data point is split into a 'stem' (the leading digit) and a 'leaf' (the trailing digit).

Front

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

Back

To read a stem-and-leaf plot, look at the stems on the left side, which represent the leading digits, and the leaves on the right side, which represent the trailing digits. Combine them to form the original data values.

Front

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 line plot?

Back

To create a line plot, draw a number line, mark the data points along the line, and use X's or other symbols to indicate the frequency of each data point.

Front

What is the purpose of using a line plot?

Back

The purpose of using a line plot is to visually display the distribution of data points and to easily identify trends and frequencies.

Front

How can you determine the number of data points from 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 relationship between a line plot and a stem-and-leaf plot?

Back

Both line plots and stem-and-leaf plots are used to display data visually, but they represent data in different formats: line plots use a number line while stem-and-leaf plots split data into stems and leaves.

Front

What is the first step in creating a stem-and-leaf plot?

Back

The first step is to organize the data in ascending order.
