Which term describes the dose that achieves the chosen response in a specified percentage of individuals?

Explanation:
Dosing concepts in pharmacology and toxicology use the idea of Effective Dose to describe the amount needed to produce a defined effect in a certain portion of the population. The term refers specifically to the dose that achieves the chosen response in the specified percentage of individuals; for example, ED50 is the dose that produces the effect in 50% of people. Other percentages (like ED20 or ED90) are used for different risk or efficacy targets. This is different from a lethal dose, which measures the amount that causes death in a percentage of individuals, and from terms describing the agent (carcinogen) or how substances interact (additive effects).
