This chapter focuses on the correlation coefficient and regression lines. If there is a functional relationship between two quantities, the shape of the curve is determined by corresponding values of the two va

Regression and Correlation Names for Correlation The correlation coefficient between two continuous variables, often called Pearson’s correlation, was originated by Francis Galton. British statistician Karl Pearson (who credits Galton, incidentally), along with Francis Edgeworth and others, did a great de...

Additionally, a form of the Pearson correlation coefficient shows up in regression analysis.R-squaredis a primary measure of how well a regression model fits the data. This statistic represents the percentage of variation in one variable that other variables explain. For a pair of variables, R-...
Standardized regression coefficient. Also termed the beta coefficient or beta weight, this is the slope obtained by the regression of Y on X when the data are standardized. Sum of squared errors. The distances of all the points from the regression line are squared and added together to arrive...
