Question

can an epidemiologist who finds a correlation between the use of tanning beds and melanoma (an aggressive form of skin cancer) in college - age women conclude that tanning beds cause skin cancer?
○ no, because correlation is not proof of causation.
○ yes, but only melanoma skin cancer, not other forms of skin cancer.
○ yes, but only for college - age women.
○ no, because the correlation would have to hold with males and females and in different age groups.
○ yes, as long as the correlation was statistically significant.

Explanation:

In epidemiology and statistics, a key concept is that correlation (a relationship between two variables) does not imply causation (that one variable directly causes the other). Just because tanning bed use and melanoma are correlated in college - age women, there could be confounding variables or other factors at play. The other options are incorrect: concluding causation just for a specific gender/age group, a specific type of cancer, or based on statistical significance alone ignores the fundamental difference between correlation and causation. Also, the idea that the correlation must hold across all genders and age groups to conclude causation is not the main reason why correlation doesn't imply causation. The core reason is that correlation doesn't prove causation.

Answer:

No, because correlation is not proof of causation.
