The Spearman correlation is another measure of the strength and direction of the relationship between two variables, but it is based on the ranks of the data rather than the actual values. A perfect positive rank correlation (i.e., when one variable always increases as the other increases) has a value of +1.00, the same as a perfect Pearson correlation. Therefore, if the Pearson correlation is +1.00, we can conclude that the Spearman correlation will also be positive and have a value of 1.00.
