Hypothesis test of Spearman’s rank correlation coefficien
3
Shula calculates the value of Spearman's rank correlation coefficient \(r _ { s }\) for 9 pairs of rankings.
Find the largest possible value of \(r _ { s }\) that Shula can obtain that is less than 1 .
A set of bivariate data consists of 5 pairs of values. It is known that for this data the value of Spearman's rank correlation coefficient is - 1 but the value of Pearson's product-moment correlation coefficient is not - 1 .
Sketch a possible scatter diagram illustrating the data.
