Meta Data: 1) Diameter of the Adult Tree: The Adult tree was set to be a tree that has a diameter larger than 50 cm. The data was collected in the unit of cm. For measuring the diameter of the tree, we did not go all the way around the tree trunk but measured the length of half of the trunk and recorded that as the diameter.
2) Diameter of the Sapling: The sapling was set to be a tree that has a diameter of less than 10 cm. like we did with the adult tree, the data was measured in cm and was collected by measuring half of the length of the tree trunk.  3) Percentage Coverage: For this data, we used our hands to make a square and held it up to the tree, and estimated how much of that square is filled with the tree leaves. This data was collected as an educated guess and therefore is less reliable than the rest of the data set.
4) Distance between the adult and the sapling trees: This data was collected, using a measuring tape (with the capacity of 30 meter), and putting it down on the ground, measured the distance between the adult tree and the sapling. the data was then recorded in cm.
This dataset was recorded  at the Danby grassland/woodland, near York University, on Wednesday September 21h 2016. The   approximate time of the recording was at 4:00 pm. The day was sunny and warm, with some clouds visible through the canopy of trees. Even though the temperature was 26 degree celsius, in the wood, the temperature felt lower and the air was cooler. There was good lighting in the wood, so that all the plants and trees were easily spotted. We measured the diameter of the adult tree (adult tree set to be a tree with diameter more than 50), the sapling (set to be one with the diameter of less than 10), the distance between adult and the sapling and the % coverage of leaves on the adult tree. The data was measured in cm. 
Material & Methods: 
The data was collected at the Danby grassland/woodland near York University, at September 21t 2016. The day was sunny and with few clouds visible and the temperature was at 26 degree celsius. The lighting was good in the wood so that the plants were easily spotted. We collected the data about the diameter of the adult tree (the adult tree was set to be a tree with diameter more than 50 cm), the diameter of the sapling (which we set to be a tree with a diameter of less than 10 cm), the distance between the adult and the sapling tree (in cm, measured by putting the measuring tape on the ground between those two and read the number using our eyes, same for all the other measurements). We also collected data about the % coverage of the leaves of the adult tree. This was done by putting our fingers together to form a square and then put it up to the sky and estimate (take an educated guess) how much of the space of that square is filled with leaves. Since this data is collected by estimating, it can be said to be less reliable than the rest of our data set, as there are more room for error and the estimation can be different form person to person. The diameter of both adult and sapling trees were collected by measuring half of the length of the tree trunk, instead of going all the way around the whole tree trunk. Hypothesis: 
We hypothesized that the more closer the sapling is to the adult  tree, the smaller it's diameter would be. And also the higher the percentage coverage of the adult tree, the smaller the diameter of the sapling, because the more leaves that the adult tree has and the closer the sapling is to that tree, the more sunlight will be cut off for that sapling. The sunlight that is required for it's growth.
Predictions:
1) saplings that are near the adult trees with large trunk, would be smaller in diameter.
2) The more leaves the adult tree has, the smaller the sapling near it would be.
