Line of best fit correlation
NettetLine of Fit. When there is a relationship between two variables, quite often it's a linear relationship, and your scatter plot will be similar to Example Plot 1, where it appears the … NettetLines of Best Fit: Students are given a scatter plot and are to informally draw and write an equation for a line of best fit. This is done by estimating not by actually calculating. They will then use the line of best fit to make predictions. Sketching Correlations: Students will sketch various scatter plots given certain correlations.
