Find the difference between the medians of version A and B.

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.
