Retention and Obliviscence as a Function of the Time
71
The average differences between times of learning and relearning at the different times of day vary somewhat with regard to their absolute values. (Of course in the case of B the number 254 must first be multiplied by 4/3, because it is derived from only 6 series.) But the relations of these differences to the times of first learning (the Q's) harmonize sufficiently well. If, therefore, all the Q's are combined in a general average, Q=33.7 (P.E.m=1.2).
