Answer:

No

Step-by-step explanation:

We can not determine that the low test scores are caused by sleep deprivation. Because there are many factors that can affect on a student's test score such as:

  • not carefully review all the lesson before the test
  • the feeling of nervous in the exam room
  • poor academic ability
  • ....so on

So, getting less than 8 hours of sleep is just one of the independent variables determining the test score, it is not a strong correlation.

Answer:

Causation cannot be proven because lower test scores can occur for other reasons, such as not studying or poor attendance.
