#3 RL (23): Graphs (line 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 read a line plot?

Back

To read a line plot, count the number of X's or dots above each value on the number line to determine how many times that value occurs.

Front

What does the highest point on a line plot represent?

Back

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

Front

What is the purpose of a line plot?

Back

The purpose of a line plot is to visually display data to make it easier to see patterns, trends, and frequencies.

Front

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

Back

To find the total number of items, add up the frequencies (the number of X's or dots) for all values on the line plot.

Front

What does it mean if a line plot has no X's above a certain value?

Back

If there are no X's above a certain value, it means that value did not occur in the data set.

Front

How do you determine the range of a data set using a line plot?

Back

The range is found by subtracting the smallest value from the largest value represented on the line plot.

Front

What is frequency in the context of a line plot?

Back

Frequency refers to how many times a particular value appears in the data set, represented by the number of X's or dots above that value.

Front

How can you compare two different data sets using line plots?

Back

You can compare two data sets by creating two line plots on the same number line and observing the differences in frequency and distribution.

Front

What is a data set?

Back

A data set is a collection of related data points or values that can be analyzed.
