Question

select the correct answer.

which statement is true about a line plot?

• a line plot shows the mean of any given data set.
• a line plot shows the first quartile, but not the second quartile of any given data set.
• a line plot shows the frequency of an interval of values of any given data set.
• a line plot shows the frequency of the individual values of any given data set.

Explanation:

Define a line plot

A line plot (or dot plot) is a graph that displays the frequency of individual data values along a number line using dots, crosses, or other marks.

Evaluate the given options

• Option 1: A line plot does not directly show the mean; the mean must be calculated from the data.
• Option 2: Quartiles are typically shown on box plots, not line plots.
• Option 3: Histograms show the frequency of intervals of values, whereas line plots show individual values.
• Option 4: A line plot shows the frequency of each individual value in the data set.

Answer:

• A line plot shows the mean of any given data set.
• A line plot shows the first quartile, but not the second quartile of any given data set.
• A line plot shows the frequency of an interval of values of any given data set.
• A line plot shows the frequency of the individual values of any given data set. (Correct answer)
