Statistics

13/06/2011. Madison I can see you have worked really hard and produced some great results. Your graphs look amazing however they are not correct. You need to group your raw data like I taught you so you have less bars on your graph! You still have not named who the average person in room 29 is!! I expect to see it by Friday you will need to do it for homework.

Taylor - Rose is the average person because in one test her name is listed under two of the averages (Mode & Median) and also her name is the only one that appears twice in one or two tests.
