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...

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. 

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...

In this scatter plots and line of best fit worksheet, students create scatter plots from given sets of data. They answer questions concerning the scatter plot. Students write the equation of a line, identify the type of correlation...

Did you know that leaky faucets waste $10 million worth of water? Conservationists perform an experiment and draw best-fit lines to explore how the US Geological Society determined this value.

Test your knowledge of linear functions and models. The last installment of a 16-part module is an end-of-module assessment task. Pupils solve multi-part problems on bivariate data based on real-world situations to review concepts from...
