Arcticwhite, ah, averages. Those are relatively simple. If you want I can help you with those:
Mean = (Sum total of all values) / (number of values)
Median = The value that appears right in the middle of all the values. If there's an even number of values and the median ends up being 2 numbers, take the mean average of those two.
Mode = The number that appears the most
Range = The range the values go, from lowest to highest
Middle school tends to be the really awkward years of growth. A lot of people are still trying to assert themselves into a niche they're comfortable with, and that can at times turn out as being cliquish or condescending to others. The patronizing tends to subside quite a bit when in high school, and goes away almost completely at college.
Don't worry Arctic; the worst of it will soon be over.
