Which of the following is true about correlation and causation
A- 2 events that happen at the same time cannot be causally related or correlated
B-Studying causation provides a clearer picture of historical events than studying correlation
C-Determining causation is a necessary step historians take before proving correlation
D-Historical narratives can be built around correlated events but not casual relationships

The correct answer is letter C

Correlation is a measure of the association between two variables. It can be calculated in several ways, each with its own applications. The most common situations in which high correlations do not indicate causality, that is, they are spurious correlations.

The first is when two things are related, and although there is no causal relationship between them, there is a cause for the two effects and from that common cause the correlation results.

Studying causation provides a clearer picture of historical events than studying correlation.
