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 read a line plot?

Back

To read a line plot, look at the number line to see the values and count the marks (X's or dots) above each value to determine the frequency.

Front

What does the highest point on a line plot represent?

Back

The highest point on a line plot represents the value that occurs most frequently in the data set, also known as the mode.

Front

What does the lowest point on a line plot indicate?

Back

The lowest point on a line plot indicates the value that occurs the least frequently in the data set.

Front

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

Back

To find the total number of data points, add up all the frequencies (the number of X's or dots) for each value on the line plot.

Front

What is the mode in a data set?

Back

The mode is the value that appears most often in a data set.

Front

How do you determine how many people did not participate in an activity from a line plot?

Back

To determine how many people did not participate, look for the value that represents non-participants and read its frequency from the line plot.

Front

What does it mean if a score has a frequency of zero on a line plot?

Back

A frequency of zero means that no data points were recorded for that score.

Front

How can you identify the score that the fewest people received from a line plot?

Back

To identify the score that the fewest people received, look for the value with the lowest frequency on the line plot.

Front

What is the significance of the number of players who won fewer than a certain number of matches?

Back

It shows how many players did not meet a specific performance threshold, which can be important for analysis.
