Answer 2

Spearman rank correlation method is used to measure the correlation between variables in a non parametric manner on the basis of data ranks.

Explanation:

Advantages of Spearman Rank Correlation:

1. One important advantage of using Spearman rank correlation coefficient is that both the independent and dependent variables are continuous and/or ordinal which eliminates the effort of converting the variables into normal distribution.
2. Spearman correlation method is extremely useful in measuring the correlation between non-linear variables.Hence, if the dependent or independent variables are non linear or the relationship between them is non-linear then Spearman correlation method is usually used.
