5.4 Line of Best Fit Given the following scatter plots, draw in your line of best fit and classify the type of relationship: Strong Positive Linear Strong Negative Linear These are the equations of the lines of best fit.

5.4 Line of Best Fit Given the following scatter plots, draw in your line of best fit and classify the type of relationship: Strong Positive Linear Strong Negative Linear These are the coefficients of determination, r 2. If we take the square root of these values we get the correlation coefficient, r. What would the r-values be in this case?

5.4 Line of Best Fit Given the following scatter plots, draw in your line of best fit and classify the type of relationship: Strong Positive Linear Strong Negative Linear r = 0.82r = In this case the negative sign is added since it’s a negative relationship

5.4 Line of Best Fit The correlation values range from -1 to 1: Perfect Correlation Strong Moderate Weak
