the mean is when you have a set of raw data and you arrange them into ascending order.
After you add all the numbers in the set of data and you divide it by how much numbers there are.
an outlier will mess up the mean.


the median is the middle number of a data set after being put to ascending order.
when you have to middle numbers you add up the numbers then divide it by two.


put the numbers in ascending order
the mode is the most common number in a data set.
you can have more than one mode in a data set.


put the numbers in ascending order
subtract the smallest number from the biggest number

Here Is a video explaining mean, median, and mode

heyy aaron! good job! but in the mean section theres a "to" thats suppose to be spelled as "two" :) and you forgot to mention one more fact about the mode. oh, and for your mean and mode links, they're the same and I don't think most people will understand what it says on that site. :) but the rest is all good. :)

Good job Aaron. But I think you should make your pictures bigger so we can see more better. Everything else was good.
