Dr. Aris is conducting a study in health psychology investigating the physiological effects of caffeine on sleep architecture. He records the average number of daily caffeinated beverages consumed by ten participants and their subsequent sleep onset latency (the duration in minutes it takes to transition from full wakefulness to sleep).
Table 1 shows the raw data from Dr. Aris's study.
| Average daily caffeinated beverages | Sleep onset latency (minutes) |
|---|---|
