## Definition

Quadratic regression is a statistical method used to model the relationship between a dependent variable and an independent variable using a quadratic function.

## Description

Quadratic regression is used to fit a quadratic equation to a set of data points, providing a model that can describe non-linear relationships. This method is useful in fields such as economics, biology, and engineering, where data often exhibit quadratic trends. In math education, quadratic regression helps students understand how to apply mathematical models to analyze real-world data, enhancing their analytical and critical thinking skills. By using technology to perform quadratic regression, students learn to interpret the resulting equation, assess the fit of the model, and make predictions based on the data. An example of quadratic regression is fitting a model to data on the growth of a population over time, where the growth rate changes as the population size increases.
