Question

question 5 of 10
if two sets of data are correlated, this means that:

a. the sampling is random.

b. there is an illusory correlation.

c. they are related, but one might not be causing the other.

d. one set causes the other to happen.

Explanation:

• Option A: Random sampling is about how data is collected, not about correlation. Correlation is about the relationship between two data sets, while random sampling is a sampling method. So A is incorrect.
• Option B: Illusory correlation is a false perception of a relationship, but the question is about actual correlation. So B is incorrect.
• Option C: Correlation means two variables are related, but it does not imply causation (one does not necessarily cause the other). This is the correct understanding of correlation.
• Option D: Correlation does not mean causation. Just because two sets of data are correlated does not mean one causes the other. So D is incorrect.

Answer:

C. they are related, but one might not be causing the other.
