Eighth graders learn to read scatter plots — plotting two variables to spot positive, negative, or no correlation — and to draw a line of best fit that models the trend and makes predictions.
Students will be able to…
Do students who study more get higher scores? A scatter plot can show whether two things are related — and let you predict. How do you read the pattern?
Project this and tap each idea. Have students learn to spot positive, negative, and no correlation — and the line of best fit!
