Re: Algebra

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.

Re: Algebra

hi Johnathon Bresly,

Welcome to the forum.  smile

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.
