Think of the mean as a fulcrum (balance point) for a distribution of scores.

I hope this helps.

D. It can be biased by one or two extremely small or large values.

The advantage is that it takes every number into account.

The disadvantage is that if you have a very large or very small number disproportionate to the rest then you calculations will be slightly off.
