good job kara! but your links for mean, median, and range says "cannot display webpage." maybe you should find different sites or ask mr.h about it. :) but anyways, good job!

and by the way, under the mean picture, it says 33/5=6.6, but in your picture it says that the answer is 4.3 repeated, just wondering what that was for. :P
