Review: Describing and comparing distributions
Please complete the practice exercises Shapes of Distributions and Describing distributions in the review lesson linked above.
For data distributed symmetrically, the mean and the median are at the same location.
What can we say about the locations of mean, median, and mode if the bimodal distribution is symmetrical?
For asymmetrical distributions (left-skewed or right-skewed), the mean follows the tail. That is the mean is pulled toward the tail by the value(s) that skew the distribution.
