= Magnitudes of dprimes for true positives and false positive rates =

The table below gives dprimes for combinations of true positive and false positive rates. Remember that a rate of 0.5, or 50%, is equivalent to merely a chance occurrence.

Dprimes greater than 2, regarded as atypical by the UCLA statistics department, are in italics.
