Hi All,
Thanks for the feedback. In response to one post, I want to let you all know that I've been diving for over 17 years. I know that air consumption rates are really complicated and there are a lot more factors to take into consideration, but this is only for a class project and the teacher agreed we needed to limit the model or it would become too difficult to manage. (FYI, my teacher is also a diver). At this point I have four variables, which si more than enough for a multiple regression analysis! Most of my classmates are only using 2 variables!
To clarify the weight issue. I meant just the weight of the diver, not with the gear included. Although that will effect the dive, it's too difficult to accurately calculate. However, if you know that when you dove last year in cozumel you weighed about 168 lbs, that's fine. It will throw the data off a bit, but weight is a very important factor in air consumption, so I felt I coudln't eliminate it completely.
As for air consumption, once again my professor said to exclude differences in gear, because there would be too many different data results that do not correlate directly. If someone weighs 160 vs 170, that's a straight scale, if someone is using one tank vs. another, they answers do not fit on the same scale, so for this level of analysis, we're ignoring that data.
For max depth, I know that max isn't as accurate as average; however, not everyone has a dive computer and not all dive computers calculate average depth, so I went with max which is easier to record. If you have average depth data, please send it to me, it will make my answers more accurate.
I've gotten a lot of great feedback, but nobody has sent me any data. I would really appreciate any help you can give. Thanks, Melanie Feller
