Alternative Hypothesis

The hypothesis that proposes there is a statistically significant difference between two data sets or a deviation from the null hypothesis.

Spearman Rank

A method that non-parametrically quantifies the rank correlation to determine how well a monotonic function can depict the relationship between two variables.
