How to interpret Spearman's rank coefficient ?!
Posted: Aug 15, 2012 2:27 PM

I have to correlate data that is not normally distributed, and also, a variable is of ordinal type. I used SPSS to estimate Spearman's rho, and have got ?(170)=0,288 (p<0,0005).

Some articles suggest interpretation of Spearman's rho similary to Pearson's correlation coefficient [Ref.: http://bold-ed.com/corrsp.htm ].

But, if so, i can't understand the following example:
In a lesson http://drbalakidd.files.wordpress.com/2011/03/spearman-rho-correlation.ppt , slide 19th, Spearman's rho of -.152 (alpha=.01) is considered strong correlation. (quoted: "Exists a significant correlation (alpha = .01) between the attitude in learning English & English language performance, which is -.152.")

Please point a refference for interpretation of Spearman Rank Correlation Coefficient.
