Question

The dot plot shows how many swimmers are in each line at a waterpark:

Dot plot titled Swimmers in Line and labeled Number of Swimmers shows a number line from 1 to 10. There is 1 dot over 1, no dots over 2, 3, 4, 5 and 6, 2 dots over 7, 4 dots over 8, 6 dots over 9, and 5 dots over 10.

Is the median or the mean a better measure of center for these data and why?

Median, because the data are skewed and there is an outlier
Median, because the data are symmetric and there are no outliers
Mean, because the data are skewed and there is an outlier
Mean, because the data are symmetric and there are no outliers

Answer 1

eliminate the answer that you know are not correct

Answer 2

From the description of the data, it seems that the data is *not* symmetric. Most of the dots are on the right side of the line, over 6, 7, 8, 9, and 10, with only a single dot over 1. The dot over 1 would be considered an outlier

Answer 3

So, what measure of center is better to use when the data is not symmetric and there is/are outlier(s)?
