This interactive, online course is the last installment in a three-part series featuring the least squares method. You will want this course in order to become expert in curve fitting with linear functions, exponential functions, and power functions.
There is a large set of examples and exercises to teach you how to determine which equation form to use in a particular analysis. You will find extensive use of two tools while you are taking this course: the hand-held calculator and the Excel spreadsheet.
