Ancient astronomers knew that the year [1] is approximately 365 days long, and we now know the correct figure is approximately 365.242 days.
Elasticity is a measure of responsiveness. The responsiveness of behavior measured by variable Z to a change in environment variable Y is the change in Z observed in response to a change in Y. Specifically, this approximation is common: elasticity = (percentage change in Z) / (percentage change in Y). The smaller the percentage change in Y is practical, the better the measure is and the closer it is to the intended theoretically perfect measure..
