If the scatterplot dots fit the line exactly, they will have a correlation of 100% and therefore an r value of 1.00 however, r may be positive or negative depending on the slope of the line of best fit. But remember, in statistics the points don’t lie perfectly on a line — the line is a model around which the data lie if a strong linear. Web the formula to determine the least squares regression line (lsrl) of y on x is as follows: In many cases, it's wise to avoid these and opt for.
