**Estimation**
**Definition**
Estimation is the process of making an approximate judgment or calculation of a value, quantity, or outcome based on available information. It is commonly used when exact data is unavailable or impractical to obtain.
**Overview**
Estimation plays a crucial role in various fields such as mathematics, statistics, engineering, economics, and everyday decision-making. It involves using known data, experience, or mathematical models to infer an approximate result. Estimations can be qualitative or quantitative and vary in precision depending on the context and purpose.
**Types of Estimation**
– **Point Estimation:** Provides a single best guess of an unknown parameter.
– **Interval Estimation:** Offers a range within which the parameter is expected to lie, often with a specified confidence level.
– **Bayesian Estimation:** Incorporates prior knowledge or beliefs along with observed data to improve accuracy.
**Applications**
Estimation is essential in project management for budgeting and scheduling, in statistics for parameter inference, and in everyday life for tasks such as time management and resource allocation. Effective estimation helps in decision-making by reducing uncertainty and guiding planning processes.
