How to use Regression In real life

  1. Sep 23, 2008 #1
    Hi, I had made an inquiry about regression last week and am still working on understanding the whole concept.This week my question is different. How would I use the a and b values of the regression to indicate how something is growing. Like I'm having problems interpreting data because I do not yet know the rules I suppose. Like if I am doing a regression expressing the mass in terms of length so m=al^b then how can i describe how a certain something is growing based on the regression. Like is there a way to say if b is less then one then mass is growing slower then length etc. Where can I find these rules on how the y axis will act based on the xaixs. Any suggestions?
