Mastering Linear Regression on TI-89
Are you ready to explore linear regression using your TI-89 calculator? In this comprehensive guide, we'll demystify linear regression calculations, empowering you to tackle statistical challenges confidently.
Understanding Linear Regression on TI-89
Linear regression is a statistical method used to model the relationship between two variables by fitting a linear equation to observed data points. On the TI-89 calculator, you can efficiently perform linear regression analysis, making it a valuable tool for statistical modeling.

Using the TI-89 Calculator for Linear Regression
- Access Regression Function: Press "APPS" followed by "Data/Matrix Editor" and select "Regression."
- Input Data: Enter the data points into lists using the calculator's keypad.
- Choose Regression Model: Select the appropriate regression model based on your data (e.g., linear regression, quadratic regression, etc.).
- Compute Regression: Press "Enter" to calculate the regression coefficients and other relevant statistics.
Examples
Example 1: Simple Linear Regression:
In this example, we'll perform a simple linear regression analysis using the TI-89 calculator. Here's how:
Result: Upon computation, you'll obtain the regression equation (Y = aX + b) along with other statistical measures that describe the relationship between the variables.

Example 2: Multiple Linear Regression:
In this example, we'll extend our analysis to multiple linear regression, where we consider the relationship between multiple independent variables (X1, X2, ..., Xn) and a dependent variable (Y).
Result: Upon computation, you'll obtain regression coefficients for each independent variable, along with other statistical measures that describe the relationship between the variables in the model.

In this example, we'll perform a simple linear regression analysis using the TI-89 calculator. Here's how:
- Accessing Regression Function: Begin by pressing the "APPS" key on your TI-89 calculator. Then, navigate to "Data/Matrix Editor" and select "Regression" from the menu.
- Entering Data Points: Input the data points into lists. For simple linear regression, you'll typically have two lists: one for the independent variable (X) and another for the dependent variable (Y).
- Choosing Regression Model: Once the data is entered, choose "Linear Regression" as the regression model. This indicates that you're fitting a straight line to the data points.
- Computing Regression: Press "Enter" to compute the regression. The calculator will analyze the data and provide you with the regression equation, which represents the best-fit line for the data, as well as other relevant statistics such as the coefficient of determination (R-squared).
Result: Upon computation, you'll obtain the regression equation (Y = aX + b) along with other statistical measures that describe the relationship between the variables.

Example 2: Multiple Linear Regression:
In this example, we'll extend our analysis to multiple linear regression, where we consider the relationship between multiple independent variables (X1, X2, ..., Xn) and a dependent variable (Y).
- Following Similar Steps: Start by following the same steps as in Example 1 to access the regression function and enter the data points into lists.
- Inputting Data for Multiple Variables: Unlike simple linear regression, in multiple linear regression, you'll input data for multiple independent variables. Each variable will have its own list in the data editor.
- Choosing Regression Model: After entering the data, choose "Multiple Regression" as the regression model. This indicates that you're fitting a linear equation involving multiple variables to the data.
- Computing Regression: Press "Enter" to compute the regression. The calculator will analyze the data and provide you with regression coefficients for each independent variable, as well as other relevant statistics such as adjusted R-squared and significance levels.
Result: Upon computation, you'll obtain regression coefficients for each independent variable, along with other statistical measures that describe the relationship between the variables in the model.
