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

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.

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?
