question 2 (mandatory) (8.34 points)
listen
to demonstrate causation one must show both correlation and ______________.
statistical analysis
a reasonable physiologic mechanism through which this occurs
scientific evidence
data comparison

Explanation:

Correlation shows a relationship between variables. But to prove causation (that one variable causes another), a reasonable physiologic (or logical in a general sense) mechanism explaining how one variable acts on the other is needed. Statistical analysis, scientific evidence, and data comparison can support correlation but don't inherently show causation. For example, if there's a correlation between ice - cream sales and crime rates (both increase in summer), without a mechanism (e.g., heat making people more irritable and also leading them to buy ice - cream), we can't say ice - cream causes crime.

Answer:

a reasonable physiologic mechanism through which this occurs
