Data-Driven Mathematics Investigations on Curved Data

Michael Bossé 

August 2005, Volume 99, Issue 1, Page 46

Abstract:
Data-driven mathematical investigations are becoming more common. Often within these investigations, one is assigned to graph data points and investigate the relationship between variables. While linear regression is a valuable methodology when the scatter plot is more or less linear, additional techniques and tools are needed when the graphed data demonstrated some curvature. This article provides three techniques for determining the equation of a polynomial function through a number of points. This function can be utilized to analyze data and provide predictions.
