E) All statements are false

Quizplus · Accepted Answer

Statement (i) is correct as correlation analysis is used to determine the strength of the relationship between two variables. Statement (ii) is correct because a correlation coefficient close to 0 indicates a weak relationship. Statement (iii) is incorrect because the strength of the correlation is determined by the absolute value of the coefficient, not its sign.
