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 . Bivariate frequency distribution. X

Testing the Significance of the Correlation Coefficient ...
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.
