SOL 5.16 - 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.

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

Front

How do you find the difference between two scores in a line plot?

Back

To find the difference, subtract the frequency of the lower score from the frequency of the higher score.

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 of the data values.

Front

How can you determine how many students scored in a specific range using a line plot?

Back

Count the number of X's or symbols that fall within the specified range on the line plot.

Front

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

Back

A stem-and-leaf plot helps to organize data while preserving the original values, making it easier to analyze and interpret.

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 and combine them with the leaves on the right to form the original data values.

Front

What is the total number of data points if a line plot shows 5 X's for score 88 and 3 X's for score 98?

Back

The total number of data points is 5 + 3 = 8.

Front

How do you calculate the total number of games played from a line plot?

Back

Add the frequencies of all the scores shown in the line plot.
