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 dots to represent each data point.

Front

How do you determine the most common value in a line plot?

Back

You look for the value that has the most marks (X's or dots) above it.

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, that helps to visualize the shape of a distribution.

Front

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

Back

Separate each data point into a 'stem' (the leading digit or digits) and a 'leaf' (the last digit), then list the stems in a column and write the leaves next to their corresponding stems.

Front

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 digit of the data values.

Front

How can you find the total number of data points represented in a line plot?

Back

Count the total number of marks (X's or dots) on the line plot.

Front

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

Back

To organize and display data while preserving the original values, making it easier to analyze the distribution.

Front

What is the difference between a line plot and a stem-and-leaf plot?

Back

A line plot displays data points along a number line, while a stem-and-leaf plot organizes data into stems and leaves to show the distribution.

Front

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

Back

Each row shows a stem with its corresponding leaves, where the leaves represent the data points that share the same stem.
