Consequently, why would you use Spearman's rank?
Spearman's Rank correlation coefficient is a technique which can be used to summarise the strength and direction (negative or positive) of a relationship between two variables. The result will always be between 1 and minus 1. Create a table from your data. Rank the two data sets.
Secondly, what is the difference between Pearson and Spearman correlation? The difference between the Pearson correlation and the Spearman correlation is that the Pearson is most appropriate for measurements taken from an interval scale, while the Spearman is more appropriate for measurements taken from ordinal scales.
One may also ask, what does Spearman correlation mean?
Spearman's correlation measures the strength and direction of monotonic association between two variables. Monotonicity is "less restrictive" than that of a linear relationship. However, you would normally pick a measure of association, such as Spearman's correlation, that fits the pattern of the observed data.
What is Pearson correlation used for?
Pearson's Correlation Coefficient. Correlation is a technique for investigating the relationship between two quantitative, continuous variables, for example, age and blood pressure. For correlation only purposes, it does not really matter on which axis the variables are plotted.
