1
●
Which of the following statements is TRUE?
A correlation of 1 or -1 implies
● causation.
Only a correlation equal to 0
● implies causation.
If the two variables of a
scatterplot are strongly related,
● this condition implies causation
between the two variables.
A high correlation is insufficient
to establish causation on its own.
RATIONALE
Recall that correlation doesn't imply causation. Causation is a
direct change in one variable causing a change in some
outcome. Correlation is simply a measure of association. It is
