Young schoolers explore the concept of linear regression. They determine the mass and density of salt water. Pupils add salt to water and record the density as salinity increases, and perform a linear regression on the data to model the...

You'll have no regrets when you use the perfect lesson to teach regression! An interactive resource has individuals manipulate the slope and y-intercept of a line to match a set of data. Learners practice data sets with both positive and...

Get your classes up and moving and learning math at the same time! Learners collect data on the length of time it takes to complete a wave compared to the number of people participating. They then create a scatter plot, calculate a...

Do homework grades really determine test scores? Learn whether lines of best fit, correlation coefficients, and residuals can be used to determine test scores when given homework grades. (It would certainly save teachers time in grading...

Do big bodies make big brains? Let your learners decide whether there is an association between body weight and brain weight by putting the data from different animals into a scatterplot. They can remove any outliers and then make a line...

Eighth graders examine the usefulness of a line of best fit by collecting and graphing data, using a graphing calculator to determine the line of best fit, and making a variety of predictions. They watch a video, then design a...

In this making predictions from data worksheet, students solve 15 short answer problems. Students determine average miles per gallon given data on miles traveled and gas used. Students make predictions using the data and a line of best fit.

In this Algebra I/Algebra II worksheet, students determine the line of best fit for a scatter plot and use the information to make predictions involving interpolation or extrapolation.  The one page worksheet contains one multiple...

Students investigate data collection and analysis.  In this Algebra I instructional activity, students create a scatter plot and find the equation of best fit in a simulation of a leaking water pipe.

In this matrices for data learning exercise, 9th graders solve and complete 29 various types of problems that include using matrices to illustrate data. First, they determine the sum, difference and scalar product for each matrices...

Students calculate the equation of the line of best fit. In this statistics lesson plan, students create scatter plots and find the line of best fit going through their data. They make predictions and draw conclusions.

In this data analysis activity, 8th graders solve and complete 4 different problems that include determining the line of best fit for each. First, they write the prediction for an equation for each situation described. Then, students...

Students identify the line of best fit. For this statistics lesson, students analyze graphs and plots to identify positive, negative or no correlation. They find the line of best fit for different scatter plots.

Students actively find the line of best fit. They gather their own data and then use a calculator to find the line of best fit, as well as the equation. They see how to use the TI 81 calculator in order to find the line of best fit.

This tutorial shows you how to enter a set of data and find the line of best fit.

The student is given actual data and asked to find a line of best fit and to give "real world" interpretations of the slope and y-intercept. A great introduction to the 83/84 and its features.

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.
