Spearman's rank coefficient helps to understand the type of correlation by looking at non-linear ranked data.
Give the formula to calculate rank correlation coefficient with (i) non-repeated ranks and (ii) repeated ranks
If precisely measured data are available the simple correlation coefficient is
(a) more accurate than rank correlation coefficient
(b) less accurate than rank correlation coefficient
(c) as accurate as the rank correlation coefficient
