It N is large the significance of Spearman's Rho can be estimated using the
T statistic.   This is what SPSS does in its NPAR TEST CORR command.  However
it is wildly inaccurate for small values of N and SPSS has taken a lot of
criticism for it.

     This is a small query I have with regard to Spearman's Rank Correlation
     using ordinal variables. There is an option to perform the test under the
     crosstab option which is great. However, the p value (significance) is not
     shown in the output.
     I've attached a screenshot of the output. Please have a look at the bottom
     most table which has the correlation values but the significance has not
     been mentioned.
     It would be great if there was a workaround through which I could estimate
     the p value as well.
     Thank you in advance
