The null hypothesis states that any effects observed after treatment (or associated with a predictor variable) are due to chance alone. Statistically, the question that is being answered is If these samples came from the same population with regard to the outcome, how likely is the obtained result?
The null hypothesis is that the Spearman correlation coefficient, Ï (rho), is 0. A Ï of 0 means that the ranks of one variable do not covary with the ranks of the other variable; in other words, as the ranks of one variable increase, the ranks of the other variable do not increase (or decrease).
