Answer:

If the class frequency (a B)=0, the value of Q will be  -1

Step-by-step explanation:

 

    If A and B are completely dissociated, then (AB) = 0 & (αβ) = 0 Thus Q = -1 i.e. Q lies between -1 to 1.

         The value of Q will be -1

  Yule's Coefficient of association : This is the most commonly used method of studying association  and it is denoted by Q and is defined by  

                                               \\\\Q=\frac{(AB)(\alpha \beta )-(A\beta (\alpha B)}{(AB)(\alpha \beta )+(A\beta )(\alpha B)}
