Texas Instruments: Run Me a Linear Regression

It's not a sprint, it's a marathon! Statistic concepts take time to develop and understand. A guided activity provides an opportunity for individuals to practice their linear regression techniques in spreadsheet software. The activity...

This activity compares children's age to height to teach linear regressions. The handout includes notes for students and teachers with a step-by-step lesson on how to do three types of linear regressions - Best Fit line, Median Line and...

In this activity, students create lists of data points, plot them on a graph, and determine the regression equation of the best fitting line. They also understand exactly how the linear regression is determined.

In this activity, students will explore finding the line of best fit based on the sum of the squares of the residuals and determine what the linear regression line is.

In this activity, students begin to investigate linear regression by looking at the effect of outliers on the regression line. The worksheet is interactive.

Students can use a graphing calculator to explore families of linear functions. This Technology Lab accompanies Lesson 5-9 from the 2007 Holt, Rinehart and Winston textbook.

Explore linear functions! In this Algebra I lesson, mathematicians graph data in a scatter plot and use a graphing calculator to find a linear regression and/or a median-median line. They use the model to make predictions.

This activity is designed to give students' practice in determining which type of test to run given certain background information. Additionally, it provides practice towards understanding the meaning of rejecting or failing to reject a...

Based off of the hit television show NUMB3RS, this two-part lesson begins by having students try to find the line of best fit for a given set of data (strike outs vs. home runs). The second part of the lesson shows how least squares...

This activity allows students to use real data obtained by them to model quadratic equations. students can use the TI-83 and/or TI-84 and a motion detector to collect their data. The students will then manually fit both quadratic and...
