d) Sample variance and Population standard deviation

3.When and why is it important to choose between the mean and median?

If the distribution is skewed, we use the median which ignores outliers from distorting the true average.

b) It really does not matter which measure of center to use, because at the end of the day you are still getting the average.

c) If the distribution is bell-shaped, we use the median, which ignores outliers from distorting the true average.
