WebPearson r correlation: Pearson r correlation is the most widely used correlation statistic to measure the degree of the relationship between linearly related variables. For example, in the stock market, if we want to measure how two stocks are related to each other, Pearson r correlation is used to measure the degree of relationship between the two. The point … WebThe coefficient of determination, r 2, is the square of the Pearson correlation coefficient r (i.e., r 2). So, for example, a Pearson correlation coefficient of 0.6 would result in a coefficient of determination of 0.36, (i.e., r 2 = 0.6 x 0.6 = 0.36). The coefficient of determination, with respect to correlation, is the proportion of the ...
