Question

laps per day
the dot plot shows the number of laps per day a swim
team completes. luca described the data as having a
spread from 10 to 60, a gap at 40, and a peak at 60.
where did luca make an error?
luca did not make an error.
the spread is from 1 to 6.
there is no gap in this data set.
the peak is at 10.

Explanation:

Step1: Analyze the spread

The spread of a data - set in a dot - plot is from the minimum value to the maximum value. In the given dot - plot, the minimum value is \(10\) and the maximum value is \(60\). So, the spread is from \(10\) to \(60\).

Step2: Analyze the gap

A gap in a dot - plot is a region where there are no data points. Looking at the dot - plot, there are no data points at \(40\), so there is a gap at \(40\).

Step3: Analyze the peak

The peak of a dot - plot is the value with the most number of data points. In the given dot - plot, the value \(60\) has the most number of dots.

Answer:

Luca did not make an error.
