Students practice informally graphing a line of best fit to a scatter plot and answer questions to determine if a scatter plot has a correlation. Students receive immediate feedback and have the opportunity to watch a video, get hints,...

Brush up on your math skills relating to the line of best fit then try some practice problems to test your understanding.

Practice explaining the meaning of slope and y-intercept for lines of best fit on scatter plots. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.

Students compare their own hand/foot span to Shaquille O'Neal's, then graph the data & construct a best-fit line. They can then use the information to investigate the proportionality of the human body.

Create your own scatter plot or use real-world data and try to fit a line to it. Explore how individual data points affect the correlation coefficient and best-fit line.

Given a scatter plot, can you estimate the slope of the line of best fit that goes through the data points? Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.

In this lesson on scatterplots, students will learn how to create the line of best fit and analyze scatterplots by learning about correlations and causation.

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...
