Median
Mean
1.2.2 Relative Positions of Mean, Median, Mode
a. Symmetrical distribution (same shape, bell shape, mean median and mode are equal)
b. positively skewed (long tail is to the right), mean is larger than median or mode
c. negatively skewed distribution (long tail is to the left, mean is smaller than median/mode)
