A clinical psychologist studying Obsessive-Compulsive Disorder (OCD) wanted to investigate the relationship between the frequency of checking rituals and the severity of obsessive doubts. She administered two standardized psychometric scales to 10 patients currently undergoing treatment.
One scale measured the frequency of checking rituals (e.g., checking locks, light switches). A high score (out of 50) indicated extremely frequent physical compulsions.
The other scale measured the frequency and persistence of intrusive, obsessive doubts (e.g., fear that a door was left unlocked). A high score (out of 50) indicated intense and persistent obsessive thoughts.
The results for each patient are shown in the table below:
Table 1: Checking rituals score and obsessive doubts score for each patient
| Patient | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
|---|---|---|---|---|---|---|---|---|---|---|

| Obsessive doubts score | 12 | 25 | 19 | 28 | 32 | 37 | 39 | 42 | 41 | 49 |
