For my initial data collection, I only looked at three trees, systematically sampled on the North side of the park, as a whole, but as my observations went on, I decided to look at each tree in five different sections from top to bottom. For each of these sections, I noted down that percentage of leave that haven’t changed color yet, and then once I have all five sections, I took the average percentage of the total leaves that haven’t changed color. Each observation was initially taken three days apart, but after some revision, I decided it would be best to take observations every one or two days as the humidity level and leaf color changes more that I anticipated. This way, I could potentially get more accurate results.
I didn’t have too much trouble implementing my design, but there definitely had to be some changes like taking observations for frequently and using a hygrometer to better measure the humidity level.
So far, my observations do support my hypothesis that when humidity level decreases, than the leaf color change increases. But there are some observations that don’t follow exactly.
