# Is a beta coefficient of 0.3441 strong?

I am wondering if there is a table or some reference that explains the strength of the beta coefficient.

Any book on regression will explain the $\beta$ coefficient.
$\beta$ refers to the standardized coefficient. It is a measure of how much the dependent variable changes when the independent variable changes by 1 standard deviation. (But see comment below about econometrics).
• In econometrics $\beta$ refers to a coefficient, standardized or not. – Aksakal May 4 '14 at 14:20
• OK, good to know. In social sciences they use $\beta$ for standardized and B for not standardized. – Peter Flom - Reinstate Monica May 4 '14 at 14:23
