HI, For attached rainfall data sheet A.Xls I want to calculate the value of correlation coefficient "r" by using Spearman correlation coefficient test. Can some one help me to calculate it in mat-lab. Moreover kindly guide me how to interpret the value of r for strong, week and negligible correlation.

if you have the statistics toolbox you can use
[RHO,PVAL] = corr(x,y,'type','Spearman')

data = xlsread('V'); [nrows, ncolumns] = size(data); for i = 1:ncolumns X = data(1:nrows-1); Y = data(2:nrows); [RHO,PVAL] = corr(X,Y,'type','Spearman'); end
