The most commonly used SDT measure of sensitivity is d’ (d prime), which is the standardized difference between the means of the Signal Present and Signal Absent distributions. To calculate d’, we need to know only a person’s hit rate and false alarm rate. The formula for d’ is as follows: d’ = z (FA) – z (H)
