Correlation is NOT about 2 variables having the exact same value – it’s about 2 variables having the same position/location on the data set. Z scores show location of scores in distribution so perfectly correlated variables will have the same z scores. Pearson’s Correlation Coefficient (r) – a measurement of linear correlation. r = (+/- 1) when there is a perfect correlation As r approaches 0, there is lack of correlation – more error. Drawing circles, or envelopes, around points o
