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

The answer is median, because the data is skewed and there is an outlier.

Answer 2

The best measure of center would be the median because the data are skewed left. The outlier would be the number 1. There is a gap between 1 and 7.
