Difference between Estimate and Estimator ?

Estimator:

It is a Random Variable. So its value depends on the outcome of some experiment, and it has a statistical distribution.

Estimate:

It's value is Constant. It is the value taken by an estimator, given a particular set of sample data.


Note:
  • One ESTIMATE will never give you multiple ESTIMATORS but one ESTIMATOR will give you multiple ESTIMATES.
  • ESTIMATOR can be a good or bad, but ESTIMATE can never be good or bad.
