Why do we do estimation?

We estimate for these reasons: To provide an order-of-magnitude size/cost/date about the project, so we have a rough idea of the size/cost/date for planning purposes. An order-of-magnitude size means we want to invest just enough time in the estimate that we believe in the accuracy of it for planning purposes.

Why do we use estimation in statistics?

Estimation is a division of statistics and signal processing that determines the values of parameters through measured and observed empirical data. The process of estimation is carried out in order to measure and diagnose the true value of a function or a particular set of populations.

What are estimation strategies?

Some of the estimation strategies are: Front-End Strategy and Closest-Ten Strategy (or rounding). Estimating sums and differences is valuable because it helps predict an answer and check a calculation. When using estimation in a problem solving context, there are important things to keep in mind.
