Key Features:

* Intuitive Descriptive Statistics:

* Quickly calculates measures of central tendency (mean, median, mode) and dispersion (variance, standard deviation, range) for ungrouped data.

* Click on each result to see its definition and clinical utility.

* Comprehensive Diagnostic Testing:

* 2x2 Contingency Table: Enter True/False Positives and Negatives.

* * Instantly calculates Sensitivity, Specificity, PPV, NPV, LR+, and LR-.

* Didactic Interpreter: Generates clear explanations for each diagnostic parameter of a specific test.

* Bayes' Theorem / Fagan Plot: Calculates Post-test Probability using prevalence and Likelihood Ratios, and visualizes it with the Fagan Plot.
