When the number of discordant pairs and concordant pairs in a P-Q relationship is equal, it means that there is no relationship between the variables. Discordant pairs are pairs in which the value of P is greater than the value of Q, while concordant pairs are pairs in which the value of P is less than the value of Q. When these two groups are equal in number, it suggests that the values of P and Q are randomly distributed and have no relationship with each other.
