Quadrat Sampling in Population Ecology
... the population to produce a good estimate. A "good" estimate should maximize both precision and accuracy. In everyday English we often use these terms interchangeably, but in science, they have different meanings. Accuracy refers to how close to the true mean (µ) our estimate is. That is, if we some ...
