Translating discrete estimates into a less detailed scale: An optimal approach

© 2019 by the Mathematical Association of Thailand. All rights reserved. In many practical situations, we use estimates that experts make on a 0-to-n scale. For example, to estimate the quality of a lecturer, we ask each student to evaluate this quality by selecting an integer from 0 to n. Each such...
