Just an extra point guys, mean is always closest to the tail of the curve!!!

in skewed curve , median is the best representative of central tendencies
in normal curve,mean is the best representative

well, in the normal curve, mean=median=mode, so either can be the best representative. Santaclara, I also noticed the obvious error the instructor made in the webprep lecture, that's why I came to find answers and found this post. :wink:
