Question

Keeping in mind that ordinal variables include continuous variables (since continuous variables have an order) Spearman’s correlation is:

		A measure of linear association between two continuous variables
		A measure of linear association between two ordinal variables
		A measure of concordance between two ordinal variables
		A measure of positive or negative association between two ordinal variables

Answer 1

Keeping in mind that ordinal variables include continuous variables (since continuous variables have an order) Spearman’s correlation is:

A measure of linear association between 2 ordinal variables .  

This association ranges from -1 to +1 ,from perfect negative to perfect positive respectively .

The ordinal variables are the variable which have 2 or more categories which can be ranked or ordered . The spearman rank corr. Checks the monotonic relationship between the variable by checking strength and the direction of the linear relations between the variable .
