good job brendan! but in your mean section, you forgot to write "divide sum by number of data" and your mean link is suppose to be a site that explains the mean, not a game. in the median section, found is suppose to be find, and i think that you could find better links for the median and mode. also, there could be only one median, not two, and explain what you're suppose to do if theres two middle numbers. but otherwise good job! :)
