Estimation is the calculated approximation of a result which is usable even if input data may be incomplete or uncertain.

In statistics, see estimation theory, estimator.

In mathematics, approximation or estimation typically means finding upper or lower bounds of a quantity that cannot readily be computed precisely and is also an educated guess . Initial results may be unusably uncertain, but with recursive input from output, can iteratively purify results to be approximately accurate, certain, complete and noise-free.

In project management, see estimation (project management).
