Question

The dot plot below shows the hourly rate of some babysitters in a city:

A number line is shown from 1 dollar to 7 dollars in increments of 1 dollar for each tick mark. The horizontal axis label is Dollar per hour. There are 4 dots above 4 dollars, 2 dots above 5 dollars, 3 dots above 6 dollars, and 1 dot above 7 dollars. The title of the line plot is Babysitting Rates.

Which statement best describes the shape of the data?

It is a cluster from $1.00 to $7.00 and has no gaps.
It is a cluster from $1.00 to $7.00 and has gaps.
It is not symmetric and has a peak at $4.00.
It is symmetric and has a peak at $7.00.

Answer 1

We can see that the $4 mark has the most points, so that would be the peak. The data is also not the same on the right and left side, so it is not symmetric. That means that the third answer choice would fit; is it the best choice?
The fourth choice is just not true; we know that the peak is at $4, not $7.
The first and second choices also can't be right, since the cluster of data does not extend from $1 to $7; all of the data points appear from $4 to $7.

Answer 2

I think so, yes
