What is the difference between an estimator and an ​estimate? A. Both an estimator and an estimate are functions of a sample of data to be drawn randomly from a population. B. An estimate is a function of a sample of data to be drawn randomly from a population whereas an estimator is the numerical value of the estimator when it is actually computed using data from a specific sample.
