Exploring Quadratic Regression on TI-Nspire
Are you ready to unlock the power of quadratic regression using your TI-Nspire calculator? In this comprehensive guide, we'll walk you through the process of performing quadratic regression efficiently, empowering you to analyze complex relationships between variables with confidence.
Understanding Quadratic Regression on TI-Nspire
Quadratic regression is a statistical method used to model the relationship between two variables by fitting a quadratic curve to the data points. Unlike linear regression, which assumes a linear relationship, quadratic regression accounts for nonlinear trends in the data, allowing for more accurate modeling of curved patterns.

Examples
Let's explore how to perform quadratic regression analysis on your TI-Nspire calculator with more detailed examples:
Example 1: Simple Quadratic Regression:
Suppose you have a dataset representing the growth of a plant over time. The independent variable (x) represents the number of days, and the dependent variable (y) represents the height of the plant. To perform quadratic regression:
Example 2: Advanced Quadratic Regression:
Consider a scenario where you have a dataset representing the trajectory of a projectile launched into the air. The independent variable (x) represents time, and the dependent variable (y) represents the height of the projectile. To perform advanced quadratic regression:
