1.	What do you mean by spearman\'s rank correlation
Answer» Spearman’s rank correlation coefficient is a non parametric variable that gives a relation between two variables . It basically gives the measure of monotonicity of the relation between two variables i.e. how well the relation between two variables could be represented using a monotonic function . The value of spearman constant varies from -1 to +1 , both inclusive . A value of +1 or -1 represents that the relationship between the two variables could be represented by perfectly monotonous functions .
