Interpreting the Correlation Coefficient r
　　0.7 < |r| ≤ 1　　　　 Strong correlation
　　0.4 < |r| < 0.7　　　 Moderate correlation
　　0.2 < |r| < 0.4　　　 Weak correlation
　　0 ≤ |r| < 0.2　　　　 No correlation

\(\normalsize\ Regression\\ (1)\ Linear:\hspace{75px} y=A+Bx\\ (2)\ Logarithmic:\hspace{30px} y=A+B\ln (x)\\ (3)\ e-Exponential:\hspace{10px} y=Ae^{Bx}\\ (4)\ ab-Exponential:\ y=AB^{x}\\ (5)\ Power:\hspace{78px} y=Ax^{B}\\ (6)\ Inverse:\hspace{73px} y=A+{\frac{B}{x}}\\ (7)\ Quadratic:\hspace{50px} y=A+Bx+Cx^2\\ \)
