I revisited the park Oct 11, 2019 at 2:13pm. The temperature was 6°C and humidity at 42%. From my previous observations, the trees looked different in all areas of the park, some were decaying while others are still mostly green. Hence, I have chosen the study how the temperature, and especially the humidity from changes in weather, are going to affect the changes in certain trees. there are three deciduous trees, comparable in size and all quite bigger than the other trees, all located along the North side of the park.
Hypothesis: The colder and dryer the weather gets over the course of Autumn, the more the leaves of the trees will change.
Prediction: As the weather gets colder and dryer, then all the leaves in each of the three trees should change at approximately the same rate.
Response Variable: Amount of color change in leaves in each tree. It will be a continuous variable as the amount of color changed leaves from green to yellow is a % of all the leaves on the tree.
Explanatory Variable: Level of humidity. It is a categorical variable as humidity will be placed in low (< 30%), medium (30-70 %), and high (>70%) levels.
