How To Store Regeq In Ti 84

How to Store Regression Equations on a TI‑84 Calculator

Storing regression equations on a TI‑84 is a fundamental skill for anyone who uses the calculator for data analysis, science labs, or math homework. By saving the equation directly on the device, you can quickly recall the model, edit it, or use it in further calculations without re‑entering the data each time. This guide walks you through every step—setting up your data, running the regression, naming the stored function, and accessing it later—while also covering common pitfalls and troubleshooting tips.

Introduction: Why Store Regression Equations?

Once you perform a regression on the TI‑84, the calculator computes the best‑fit line (or curve) and displays the regression equation along with statistical measures such as r². On the flip side, the equation only appears on the screen; it isn’t automatically saved as a usable function. Storing the equation lets you:
