(08.06)The dot plot shows how many attempts it took for each student to complete a puzzle:
Dot plot titled Puzzle Attempts and labeled Number of Attempts shows number line from 1 to 10. There are no dots over 1 and 10, 1 dot over 2 and 9, 2 dots over 3 and 8, 3 dots over 4 and 7, 5 dots over 5 and 6.
Is the median or the mean a better measure of center for these data and why?
Mean, because the data are skewed and there are outliers
Mean, because the data are symmetric and there are no outliers
Median, because the data are skewed and there are outliers
Median, because the data are symmetric and there are no outliers
