Pearson r. There is a simple and straightforward way to measure correlation between two variables. It is called the Pearson correlation coefficient (r) – named after Karl Pearson who invented it. It's longer name, the Pearson product-moment correlation, is sometimes used. The formula for computing the Pearson r is as follows:

Also, find Karl Pearson's correlation coefficient. Test its significance. Solution. Let, X and Y be age of husband and wife respectively. We observe that the variable X takes the values from 24 to 28 and Y takes the values from 17 to 20. We obtain the bivariate discrete frequency distribution given as .

The significance test for r evaluates whether there is a linear relationship between the two variables in the population. The appropriate correlation coefficient depends on the scales of measurement of the two variables being correlated. There are two assumptions underlying the significance test associated with a Pearson correlation coefficient ...
