The correlations on the main diagonal are the correlations between each variable and itself -which is why they are all 1 and not interesting at all. The 10 correlations below the diagonal are what we The Pearson’s r for the correlation between the water and skin variables in our example is 0.985. When Pearson’s r is close to 1… This means that there is a strong relationship between your two variables.
