Collection 5:

 This graph shows the Least-Squares line of manganese compared the percentage of leaf canopy. As you can see, the line shows as the average coverage increases, the level of manganese decreases proving our hypothesis true. This data proves that 33% of tests taken of manganese compared to canopy percentage will be tested positive according to our hypothesis. On the residual plot, the dots representing data points show how accurate the data is. Plotted points should be evenly distributed in order to show that the increasing level of canopy makes the manganese decrease a precise statement.

Collection 6:

Ferric iron and the percentage of canopy is compared in this graph. The Least-Squares line show the general pattern of the plotted data points. This proves that as the canopy percentage increases, the level of ferric iron decreases proving our hypothesis true. Even more than collection 6, 42% of all tests taken comparing ferric iron and canopy percentage should be proven correct. The residual plot supports this accuracy showing two plotted points above line 0 and two points below. Three of the four data points seem accurate, but one proves different.

Collection 7:

 This graph shows the Least-Squares line of manganese compared to the average ground leaf coverage. The line clearly shows the patter of the plotted data points, proving our hypothesis true. As the percentage of ground coverage increases, the levels of manganese decrease. The percentage of accuracy is extremely high compared to the other collections. 82% of all tests is predicted to supportive of our hypothesis. Although two plotted points seem above line 0 on the residual plot, they are closely plotted along accuracy. Also, the two other points are at a relative distance above and below line 0.

Collection 8:

Collection eight's graph shows the Least-Square's line of ferric iron compared to the average percentage of ground coverage. Like all other graphs, this also proves our hypothesis true showing the decreasing percentage of ferric iron with increasing ground coverage. This data proves that 51% of all tests comparing ferric iron and percent ground coverage will be correct according to our hypothesis. The residual plot shows two points almost exactly on line 0 while the two other points are at an equal distance above and below line 0.
