The correlation coefficient is 0.6341.360 0.4941.446.

This K 1 is the sum of the corresponding correlation values of each column. For example, the value of K 1 in the first column of a column is (1.27+3.08+4.18)/3 is the value of K 1, and so on, the small value of k is the corresponding sum not divided by 3.

That's about it.
