A table for the calculation of d' and BETA.

The methodology of signal detection theory is a preferred technique for assessing an S's ability to discriminate the occurrence of discrete binary events. A compact table is presented which will permit precise calculation of signal detection parameters, d' (discrimination index) and BETA (response bias), for hit and false alarm rate combinations in the range from .01-.99.
