5	M	W	14
6	F	H	26
7	M	B	11
8	F	W	8

A) Calculate ALL POSSIBLE measures of CENTRAL TENDENCY for the WEIGHT LOSS variable (15pts).

B) Calculate ALL POSSIBLE measures of CENTRAL TENDENCY for the variable RACE (10pts).

C)CalculateALL POSSIBLE measures of VARIATION for the variable the WEIGHT LOSS variable (20 pts).
