Spend some time with lines of best fit. An informative unit has learners investigate government spending. They research data on poverty, educational spending, social security, and defense spending, and then analyze lines of best fit for...

Can I afford to go to college? Small groups design a method to research college tuition for several years and make a prediction of costs in 2025. Classmates plot the the data on a scatter plot and graph the line of best fit to make their...

Don't let a great resource scatter to the winds. Pupils analyze two sets of test scores on a scatter plot. They draw a line of best fit and use it to make predictions about the test scores. They also consider any apparent trends in the...

You aced the first test, so your score on the second one shouldn't matter, right? Young pupils first draw a best fit line on a provided scatter plot showing test scores for two different tests. They then evaluate five...

Mississippi has both the highest obesity and poverty rate in the US. Does the rest of the data show a correlation between the poverty and obesity rate in a state? Learners tackle this question as they practice their skills of regression....

Finally! Math and Instagram have come together to discuss the correlation between likes and followers. High schoolers can't help but want to discover what makes one account more popular than another by developing a line of best fit and...

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...

Population density, it is not all that it is plotted to be. Pupils analyze a scatter plot of population versus area for some of the states in the US. The class members respond to eight questions about the graph, specific points and...

Serve four towns with one bus route. Pupils develop a bus route that meets certain criteria to serve four towns. They determine which of the routes would best serve all of them. Individuals then hypothesize where a fifth town should be...

In this least squares approximation instructional activity, 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...

In this data analysis worksheet, 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...

What linear equation will fit this data, and how close is it? Through discussion and partner work, young mathematicians learn the procedure to determine a regression line in order to make predictions from the data. 

More people, more garbage! Young environmentalists graph population growth against the amount of garbage generated per year and find a linear model that best fits the data. This is an older resource that could benefit from more recent...

Let's go fishing together. The lesson looks at the giant catfish from two perspectives. Mathematically, pupils develop a scatter plot and a best-fit line for the size, while others take a scientific look at the reasons for their...

Objects may be more linear than they appear. Scholars investigate the relationship between the number of bone mineral density scanners in the US and time. Once they take the natural logarithm of the number of scanners, a linear...

Seeing is believing. Given several bivariate data sets, learners make scatter plots using the online SeeIt program to visualize the correlation. To get a more complete picture of the topic, they research their own data set and perform an...

In this math worksheet, students identify the type (if any) of correlation on 6 scatter plots. They use information given on a table to create a scatter plot and identify the type of correlation. Students use the scatter plot to make...

Students identify the line of best fit. In 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.
