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.
Of course that result can be rigorously obtained, but who cares?
Combinatorics is Algebra and Algebra is Combinatorics.

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.
