sci.signal-detection-d-prime Calculator
Calculates d' (d-prime) signal detection sensitivity = (µsignal − µnoise)/σ from hit rate and false alarm rate, separating sensitivity from response bias. d' = 0 means chance performance; d' = 3 is excellent detection — d' is independent of the response criterion unlike hit rate or accuracy.
Inputs
Hit Rate Pct
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
False Alarm Pct
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
Results
d\
Reference formula or conversion factor shown for context.
response bias c
Sample size or count used in the calculation.
