Can anyone provide a little help with high school maths? Question: I have been given the following data set: (0, 4.2), (1.5, 5.7), (3, 8), (4.5, 10.7), (6, 14) And I've been told to "Generate values for the parameters in the linear, quadratic, cubic and exponential models." Now I'm not (necessarily) looking for the answer here but only a way in which to concor this question. Quite frankly I have no idea where to start except so far I have graphed the plots. Note: The graph is not linear Answer: Fitting Functions to Data: Linear and Exponential Regression http://people.hofstra.edu/Stefan_Waner/RealWorld/calc topic1/regression.html Check your answers here Simple Regression Utility http://people.hofstra.edu/Stefan_Waner/RealWorld/newgraph/regre ssionframes.html Using a calculator http://www.adventures-in-education.com/Books/Linear%2 0Regression%20and%20Curve%20Fitting.htm Regression with Microsoft Excel http://www.abac.edu/math/Excel%20Regression.pdf |
