Adjusted R Square is no different than R Square.

An Adjusted R Square reflects the number of independent variables and the sample size, and may increase or decrease as independent variables are added or dropped from a multiple regression model

A regression model with a low R Square is a better performing predictor ofythan one with a high R Square.

Adjusted R Square measures thehomoscedasticityin cross-sectional data.
