Analysis of Variables (ANOVA) – Tukey’s Post-Hoc Test (Power Analysis)
There is no statistically significant difference in branch angles between the 20 trees. This means that the data is 96.4% accurate in terms of the trees in an individual quadrant. The probability value was 0.964. It is 99% certain that the angles are all within ten degrees of each other, 52% certain that the angles are all within five degrees of each other and 6.5% certain that they are all within one degree.

One Sample T-Test (Mean MU = 90)
There is more than a 99.9% chance that the mean of all the angles is very close to 90°.

Standard Deviation (n) Test
The standard deviation for all the branch angles is 14.26739626, indicating that the data is not generated randomly, and is accurate, since the bell curve is small.
