Unformatted text preview: positive kurtosis (shown on attachment 2). I also notice that PH has an incredibly small spread, starting at a bin of about 6 and going to a bin that is slightly over 8.5 (shown on attachment 2). * To determine the skew of the above variables, I looked at the graph and observed to which side the bins peaked at, a left peak indicates a right skew, a right peak indicates a left skew, and a middle peak would just be normal skew or zero. To determine the kurtosis of the variables I observed the actual peak of the graph, a large peak meant a positive kurtosis, a low peak meant a negative kurtosis, and an average peak indicated a normal kurtosis. The following chemicals elements have a high correlation to THA (shown on attachment 3): • CA  0.955599 • MG  0.942599 For CA: The equation for my R 2 value Is, R 2 = 0.9132 My Significance F value is, y = 0.2172x + 4.8543My R 2 value for CA is a high goodness to fit value.My Significance F value is significantly valid....
