Question

If   is 0.35,then

Accepted Answer

A) the proportion of variance in the population accounted for by the relationship we've discovered is   = .1225 or 12.5%. 
B) we are 35% more accurate at predicting subjects' scores when we use the grand mean to predict scores rather than using the mean from the condition they are in. 
C) we are 35% more accurate at predicting subjects' scores when we predict the mean score from the condition they are in rather than using the grand mean. 
D) we are 35% less accurate at predicting subjects' scores when we predict the mean score from the condition they are in rather than using the grand mean.
