Unformatted text preview: Correlations Correlations Lecture Five Lecture Five Spring 2008 Spring 2008 Correlation (r) Correlation (r) Mathematical technique to determine the relationship between two sets of scores. Pearson Product-moment Pearson Product-moment Correlation (r) Correlation (r) Estimates the linear relationship between variables. The Mathematical Technique The Mathematical Technique Karl Pearson Karl Pearson The degree of relationship The degree of relationship Magnitude (strength) of r Magnitude (strength) of r How close r is to +1.00 or -1.00. Higher absolute value of r, the stronger the correlation. r = +1.00 -- perfect positive correlation. r = -1.00 -- perfect negative correlation. Factors that influence magnitude of r: Factors that influence magnitude of r: Linearity If the relationship between two variables is curvilinear, Pearson r will underestimate the true relationship....
