Students will explore the data on boat registrations and manatee deaths in Florida. They will use the data, the graph of the data and the line of best fit to make predictions about the relationship of the data.

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...

Students perform an experiment that simulates a leaking pipe and gather data on volume of water lost over time. They graph the data collected as a scatter plot, find the equation of the line of best fit, find the total volume of water...

This task looks at a possible relationship between the weight of an animal's body and the weight of its brain. Students make a scatter plot of data, look for outliers, make a second scatter plot without the outliers, and describe the...

Students determine how the temperature of water affects the dissolving time of a sugar cube. They create, interpret and analyze graphs of data, find an equation of the line of best fit, and relate slope to rate of change.

Students calculate a linear regression model using a graphing calculator. The given points are available in PDF format.

Students calculate a linear regression model using a graphing calculator. The given points are available in PDF format.

This lesson explains that lines of fit are estimations and may differ.

[Free Registration/Login may be required to access all resource tools.] Learn how to write equations of best fit lines.

Young scholars are introduced to the "Walk the Line" challenge question. They are asked to write journal responses to the question and brainstorm what information they need to answer the question. Ideas are shared with the class (or in...

The mathematics resource assesses students on linear relations. The activity has problems with graphing and analyzing linear relations. Some of the topics included are variation, scatter plots and linear relationships. The worksheet has...

Given a scatterplot where a linear function is the best fit, the student will interpret the slope and intercepts, determine an equation using two data points, identify the conditions under which the function is valid, and use the linear...

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 plan on how to do three types of linear regressions - Best Fit line, Median Line...

[Free Registration/Login may be required to access all resource tools.] This lesson covers plotting a scatterplot and finding a linear equation that best fits the data.

Explains, with examples, what scatter plots are and how to interpret the data. Discusses trends, interpolation and extrapolation, and correlation. Includes a set of practice questions.

Five problems present practice using data to write equations and linear models. They are given with each step to the solution cleverly revealed one at a time. You can work each step of the problem then click the "View Solution" button to...

Find activities here for linear functions, slopes and regression lines. Use them for classroom work or individual assignments.

Young scholars use weight to collect data and investigate the linear relationship. This activity uses a graphing calculator.

[Free Registration/Login may be required to access all resource tools.] In this lesson students draw a scatter plot of data, find and draw the function that best fits that data, and make predictions from that information. Students watch...

This lesson introduces students to Activity Center and introduces students to the use of symbolic algebra to represent real world situations. They will use Activity Center to contribute equations that model a linear relationship and then...

Students determine the relationship between the stretch of a spring and the number of weights in a cup suspended from the spring. They find the Y-value of a function if the X-value is provided. They use technology to plot a set of...

Using the USA TODAY Infograph, "More students apply early," students will explore scatter plots and independent and dependent variables. Students will determine a best-fit regression model for the real-life data set and then use the...

[Free Registration/Login may be required to access all resource tools.] Use a calculator to create a scatter plot and to determine the equation of the line of best fit.

Three lessons on different types of data (qualitative, quantitative, univariate, bivariate, biased data) as well as a practice activity and teacher resource.
