Question

When is rank correlation more precise than simple correlation coefficient?

Solution

Rank correlation is more precise than simple correlation when the variables cannot be measured meaningfully as in the case of price, income, weight etc. Ranking may be more meaningful when the measurement of the variables are suspect. Ranking may be a better alternative to quantification of qualities.
