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 total number of students in a class using a line plot?

Back

Count the total number of marks (X's) on the line plot to determine the total number of students.

Front

What does the highest number in a stem-and-leaf plot represent?

Back

The highest number represents the maximum value in the data set being analyzed.

Front

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

Back

Look for the mark corresponding to that grade on the line plot and count how many times it appears.

Front

What does each 'stem' represent in a stem-and-leaf plot?

Back

Each 'stem' represents a group of values that share the same leading digit(s).

Front

What does each 'leaf' represent in a stem-and-leaf plot?

Back

Each 'leaf' represents the trailing digit of the numbers in the data set.

Front

How do you interpret a line plot with multiple data points?

Back

Each data point's frequency is shown by the number of marks above it, indicating how many times that value occurs.

Front

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

Back

The purpose is to organize and display data while preserving the original values, making it easy to see the distribution.

Front

How can you find the mode of a data set using a line plot?

Back

The mode is the value that appears most frequently, which can be identified by the highest stack of marks on the line plot.
