The given distribution is skewed left. Compare the median and the mean.

• The median and the mean are the same because they both are measures of center

• The median is less than the mean since the distribution is skewed left.

• The median is greater than the mean since the distribution is skewed left.

• There is not enough information to compare the median and the mean.

The mean gets pulled away from the center of data or the typical value when the data is skewed to the right or left.
