Help! I need this for a discussion!!!

Create one symmetrical (normal) and one asymmetrical set of data, and explain why each fit the definition.

+ Knowing the type of distribution and the skewness of the data, is it possible to draw conclusions about the mean and the median?

+ Why would it be best to use particular measures of center and spread if the data is symmetrical or asymmetrical?

+ What measures would you use in each case?
