This has the effect of compensating for the number of variables in a model, and consequently, the Adjusted R2 value is almost always smaller than the R2 value. However, in making this adjustment, you lose the interpretation of the value as a proportion of the variance explained.

ANOVA for Regression. Analysis of Variance (ANOVA) consists of calculations that provide information about levels of variability within a regression model and It is the squared value of correlation coefficient. It is also called co-efficient of determination. This is often used in regression analysis, ANOVA etc. analysis. The Nov 21, 2011 What is R2?

Typically, you’d use regression analysis to obtain the slope and correlation to obtain the correlation coefficient. These statistics represent fairly different types of information. The correlation coefficient (r) is more closely related to R^2 in simple regression analysis because both statistics measure how close the data points fall to a line. I was also going to say 'neither of them', so i've upvoted whuber's answer.
