The Jordan totient J k (n) can be defined by J k (n)= n k∏ p| n (1− p− k). In this paper, we study the average behavior of fractions P/Q of two products P and Q of Jordan totients, which we call Jordan totient quotients. To this end, we describe two general and ready-to-use methods that allow one to deal with a larger class of totient functions. The first one is elementary and the second one uses an advanced method due to Balakrishnan and Pétermann. As an application, we determine the average behavior of the Jordan totient quotient, the k t h normalized derivative of the n t h cyclotomic polynomial Φ n (z) at z= 1, the second normalized derivative of the n t h cyclotomic polynomial Φ n (z) at z=− 1, and the average order of the Schwarzian derivative of Φ n (z) at z= 1.
