Sample Results
The following are
examples of graphs and charts of data from our research.The first three
figures show all the data from all the days in a scatter plot. These
graphs are meant to show the significance of the distance from the tree.

Figure 1: Nitrite Graph |
Figure 2: Nitrate Graph |
Figure 3: Ammonia Graph |
The graph on the left shows an example of a comparison of the averages of the levels of nitrogen. The chart on the right shows the P-values of the different kinds of nitrogen from one location to another. The P-values are used to determine if there is a significant difference in the levels of nitrogen between each distance from the tree. They were found by performing a T-test. If you would like to know how to complete a T-test, here's how: http://www.excel-easy.com/examples/t-test.html |
