ED: Confusion Matrix Workbench
This interactive page uses a 2x2 integer count table to summarize binary outcomes in experiment and measurement workflows.
Enter counts for:
- true positive (TP)
- false positive (FP)
- false negative (FN)
- true negative (TN)
The tool calculates prevalence, accuracy, precision, recall, specificity, negative predictive value, and F1. The distribution chart compares key rates so you can quickly see whether error is concentrated in false positives or false negatives.
Use this alongside the notebook chapter: Confusion Matrix for Experiment Readouts.
