Estimation
- Provides an approximate value when exact measurement is not possible or practical.
- Helps plan resources and decisions (e.g., ordering materials, forecasting weather).
- Relies on knowledge, measurements, past data, and experience to produce a reasonable approximation.
Definition
Section titled “Definition”Estimation is the process of making an educated guess or approximation about a value or quantity.
Explanation
Section titled “Explanation”Estimation is used when exact measurements are unavailable or impractical. It is a practical skill applied across many fields and enables informed decision-making and planning. The process typically combines available measurements, relevant data, and the estimator’s knowledge and experience to arrive at an approximate value.
Examples
Section titled “Examples”Construction
Section titled “Construction”A contractor estimating the number of bricks needed to build a wall would measure the wall’s dimensions and calculate the total area, then divide that by the size of each brick to determine the approximate number of bricks required. This estimation allows the contractor to order the appropriate amount of materials and plan work accordingly.
Weather forecasting
Section titled “Weather forecasting”A meteorologist estimating the likelihood of precipitation for a particular location on a given day analyzes data from past weather patterns, current atmospheric conditions, and other factors to make an educated guess about the likelihood of rain or snow. This estimation helps people plan activities and make informed decisions about safety and comfort.
