Pearson's Correlation Coefficient (r)

Incorrect. While correlation is a useful tool for describing the relationship between 2 variables it does not serve as a test of our hypothesis. If we were to calculate the correlation between scores for Belize and Samoa, we could get an r value. However, this value would have no real meaning as it would describe the linear realtionship between the scores, but, provide no information regarding similarities or differences between the two cultures. In general, correlations are only appropriate when we are interested only in the relationship of two dissimilar variables (e.g. income and age) rather than two very similar variables.
