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 of best fit to show whether the relationship is positive or negative.

Lines of Best Fit
High schoolers determine if there is an associationm in a scatter plot of data. They analyze data through predictios, comparisons, and applications. Students calculate the line of best fit using a graphing calculator. They display data in charts and graphs and approximate the line of best fit.

Line of Best Fit
Students explore the concept of linear regression. In this linear regression lesson, students do a Barbie bungee activity where they collect linear data. Students plot their data using a scatter plot. Students determine a line of best fit for their data by performing a linear regression on the data.

Linear Modelling of the Life Expectancy of Canadians
Middle and high schoolers explore the concept of linear modelling. For this linear modelling lesson, pupils find the line of best fit for life expectancy data of Canadians. They compare life expectancies of men and women, and find the point of intersection when males and females have the same life expectancy.

Strike a Pose: Modeling in the Real World (There's Nothing to It!)
Adjust this instructional activity to fit either beginning or more advanced learners. Build a scatter plot, determine appropriate model (linear, quadratic, exponential), and then extend to evaluate the model with residuals. This problem uses real-world data and challenges one to make predications based on the model.

Line of Best Fit
Students collect data, analyze their data and draw conclusion. In this statistics lesson, students identify different patterns through graphing. They make predictions using these patterns and the line of best fit for the future. They approximate the line of best fit using two points.

Linear Systems: Least Squares Approximations
In this least squares approximation worksheet, students determine the number of solutions a given linear system has. They find the least square error and the equation of a line of best fit for a set of three points. Students find the equation of a parabola of best fit through a given set of points.

Line Of Best Fit
Eighth graders investigate using scatter plots to illustrate the data found in sets. Then they connect the coordinate points in order to find the correct line. Students make estimations of the second variable when given the first. They work in small groups in order to prepare for an assessment.

Bivariate Data – Grade 11
Eleventh graders determine a line of regression and coefficient of correlation for bivariate data. In this Algebra II lesson, 11th graders determine the relationship between the regression line and the correlation coefficients. This review lesson provides an opportunity for students to learn the material in a different way, including visually and symbolically.

Taking Its Toll
Students explore the concept of toll roads. In this toll roads lesson, students determine the per-mile charge for a car to travel on a toll road. Students collect cost and distance data on toll roads in Pennsylvania. Students pick two data points and determine the slope of the line.

Using Data Analysis to Review Linear Functions
Using either data provided or data that has been collected, young mathematicians graph linear functions to best fit their scatterplot. They also analyze their data and make predicitons based on the data. This lesson is intended as a review of linear functions.
