A researcher is comparing the number of books read by students in two different classes. One class has a right-skewed distribution of books read. Which measure of center is most appropriate for comparing the two classes?

Mean, because it includes all data points.

Median, because it is less affected by extreme values.

Mean, because the data is skewed.

Median, because it is always easier to calculate.

When comparing housing prices in two different neighborhoods, why is the median price generally a more reliable measure of the 'typical' house price than the mean price?

Because housing prices are always symmetrically distributed.

Because the mean price is always lower than the median price.

Because a few very expensive houses can significantly increase the mean.

Because the median is calculated from a larger sample of houses.

The mean and median are both equally affected.

The median is increased significantly more than the mean.

The mean is increased significantly more than the median.

Neither the mean nor the median is affected.
