1. a statistical unit of measurement used in analyzing dose-response relationships, especially in toxicology and pharmacology
Usage: statistics; technical

Examples

• The researcher used probit analysis to determine the lethal dose.
• Probit models are commonly applied in bioassay studies.
• The probit transformation converts percentages to a linear scale.
• Scientists calculated the probit value for each concentration level.
• The probit method helps estimate effective doses in experiments.
