Which of the following statements is the leastaccurate concerning correlation analysis?
A) Correlation does not imply causation.
B) The correlation coefficient captures only a linear relationship.
C) The correlation coefficient may not be a reliable measure when outliers are present in one or the both of the variables.
D) The correlation coefficient describes both the direction and strength of the relationship between two variables only if the two variables have the same units of measurement.

Question

Quizplus · Accepted Answer

The statement in option D is the least accurate because the correlation coefficient describes both the direction and strength of the relationship between two variables regardless of whether they have the same units of measurement. The correlation coefficient ranges from -1 to 1 and captures both the direction (positive/negative) and strength (weak/moderate/strong) of the relationship between two variables. It is not affected by the units of measurement of the variables being correlated. Options A, B, and C are accurate statements about correlation analysis.
