A popular tool to help practitioners and students convert between normalized measures, and perform calculations against several detection theories.

There are also two online calculators, one for Normal Curves, one for Detection Theory, as well as a normal curve range visualization tool.


How it works

The Normal Distribution Curve Calculator is based on the Normal/Gaussian curve, like many neuropsychological (and other standardized) instruments.

Many neuropsychological tests convert to and from normal curves with different means and standard deviations. NormDist makes the appropriate conversions to allow quick comparisons between the results of the various tests.

Signal detection theory also relies on two normal curves, and offers several computations based on the different characteristics of the two.
