Hi;

http://en.wikipedia.org/wiki/Regression_analysis

Basically it is curve fitting. Finding the realtionship between variables. If you know what a graph is then you will know what I mean.

It is much easier to understand with an example. Did your teacher give you one?

In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

hi Johnathon Bresly,

Welcome to the forum.

Our very own MathsIsFun leader has also made some pages on this although the term 'regression' is not used.

Have a look at

http://www.mathsisfun.com/data/scatter-xy-plots.html

Regression analysis is a way to calculate a 'line of best fit'.

Often you will meet problems where the line is straight, but this is not a requirement.

Trying to fit a curve is more difficult.

The limit operator is just an excuse for doing something you know you can't.
