WISE » Signal Detection: d’ Defined - Claremont Graduate …
- https://wise.cgu.edu/wise-tutorials/tutorial-signal-detection-theory/signal-detection-d-defined-2/
- 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) where FA and H are the False Alarm and Hit rates, respectively, that correspond to right-tail probabilities on the normal distribution.

dprime analysis - The Center for 17th- & 18th-Century Studies
- http://phonetics.linguistics.ucla.edu/facilities/statistics/dprime.htm
- The statistic d' ("d-prime") is a measure of this difference; it is the distance between the Signal and the Signal+Noise. However, d' is not simply H-F; rather, it is the difference between the z-transforms of these 2 rates: d' = …
Lesson 8: Signal Detection Theory and the 'yes/no' experiment
- https://courses.washington.edu/matlab1/Lesson_8.html
- D-Prime can be estimated using a simple forced-choice method by assuming Signal Detection Theory with a fixed criterion. The goal is present both signal and noise trials and calculate the proportion of hits and …
Signal detection theory: How to calculate c' when d' is 0?
