Correlation is a measure of the relationship between two variables using the
ranked data. Spearman's rank correlation is the number r, given by the formula
r = 1 - 6 Σ d²
n (n² - 1)
Where d is the difference of the corresponding ranks and n is the number of
pair’s observation. In the present study, literacy is considered as an
independent variable, while sex ratio is considered as a dependent variable.
