Calculating SSE in a TI-84 Calculator

these days much of mathematics comes down to how well you know your calculator. Calculators are by far the greatest invention to come into my life. As many of you have already found out… It’s why I am what I am now. Statistical analysis is a pretty broad topic, covering things from standard deviation to sums to todays topic, SSE. Given a plot of data (x,y), the SSE stands for the Sum of the Squares of the Error, and they represent the failure of a given line to fit that data. If you jump into Excel or some other graphing utility and plot a series of data you may see a pattern emerge. Most utilities provide a method to find a line that fits the data (usually in the linear mx + b format), and you will obviously use this form today.

Lets get started…
