What is the only way in which we can determine causation?
Correlation, see solution.
Let's recall how causation can be determined.
|
Causation can only be determined from data collected from a controlled experiment. |
In this situation, a survey showed a positive correlation between sleeping with the light on and nearsightedness. It was not a controlled experiment. Thus, it does not illustrate causation, but only correlation.
Let's think of other factors that might be involved. Age, genetics, and the lifestyle of each individual might be the cause of nearsightedness.
