This 10 question assessment is set up for MYP Years 3-5 and aligns with Criterion D: Applying to Real Life Situations. It includes finding a linear regression equation, using it to predict values, assessing the reasonableness based on the correlation coefficient, interpreting the slope in the context, and finding a best fit line by hand and comparing the line by hand with the regression line. You could also use this as an activity to review linear regression for older students.
