This isn't some dumb-downed whitewash. It's a must-read for a beginner taking his or her first steps toward understanding stats. Various statistics are used to estimate parameters of a population.
Estimators have different properties.
One properity is bias. Minimum bias estimator would be the estimator out of a group of estimators with the minimum bias. That makes it good in one sense, but not necessarily in other ways. If you are not a math or statistics major, I doubt anyone would bring it up. All rights reserved.
