it's been awhile since i've taken statistics and i've forgotten how to calculate t. can anybody help me?
Spearman's rho is a measure of the linear relationship between two variables. It differs from Pearson's correlation only in that the computations are done after the numbers are converted to ranks. When converting to ranks, the smallest value on X becomes a rank of 1, etc. Consider the following X-Y pairs:
X Y 7 4 5 7 8 9 9 8
X Y 2 1 1 2 3 4 4 3
