   Question

   In research with 6 subjects, the Wilcoxon test on the difference in mean rank orders. The subjects were randomly assigned to one of two conditions. Two observers indicated with numbers from 0 to 10 the extent to which "restless person” applied to the subjects, where 0 “very calm person” and 10 means “very agitated person.” The observers did not know not which condition each of the subjects was in. The data from observer 1 are as follows:______________________. group 1: 6, 2, 3 Group 2: 4, 5, 1. The data from observer 2 are as follows. group 1: 10, 6, 7 Group 2: 8, 9, 4. Rankings are made of the dates for each of the observers, where a high rank is assigned to a high score (10 gets rank 1, etc.). It then follows that the average rank orders

   
   
   1. TRUE: Are equal for both observers.
   2. FALSE: Of observer 1 are larger than that of observer 2.
   3. FALSE: Of observer 1 are smaller than that of observer 2.
   
   
   1. Be the same for both observers…: Correct
   2. Of observer 1 are larger than those of observer 2.:Incorrect
   3. Of observer 1 are smaller than that of observer 2.: Incorrect
