Very nicely done. My only question regards the choice of 5.0 per minute as the boundary for spikes. First, I think it could help if you explained how many spikes you found and filtered out using this method. Second, I would like to know a few more details as to how you came to choose 5 as the boundary point. If you could include the plot you reference on the original page, I think that would make the decision-making process much more clear. I do have one concern with your graphing methodology, as well - how do you rule out the possibility that the 10 hours examined were not representative of the week as a whole? If they were from midnight to 10 am on a day when the participant had class, for example, I would assume there would be much less activity than during the afternoon or during hours when the participant was typically physically active. This could mean that much of the participant's physical activity would not be reflected in your conclusions. On the other hand, it is possible that you chose a perfectly representative 10 hour sample and the cutoff of 5.0 is entirely reasonable to eliminate the spikes. For this reason, I think some additional information supporting your reasoning to choose 5.0 as the cutoff would be helpful.

I agree, this is very impressive! I really like the formatting of the programs. I agree with all of Mike's concerns, particularly that a few more details in the description would make some of their decisions more clear. LucieColeman (talk) 16:14, 23 January 2013 (UTC)
