Upon the request to assign a vote from 1 to 5 to each of the four photographs, people responded as presented in Figure 21.  
The average score for picture 1 was 2.49, that for picture 2 was 3.31, that for picture 3 was 4 and that for picture 4 was 2.9.  
The patient herself voted separately on every picture, and the results were:
