Question

Quizplus · Accepted Answer

When a correlation is perfect and positive, the correlation coefficient r is equal to 1.00. Therefore, option A is correct. Option B (r = .00) is incorrect because a correlation of zero indicates no relationship between the variables, not a perfect positive relationship. Option C (r = -1.00) is incorrect because a correlation of -1.00 indicates a perfect negative relationship, not a perfect positive relationship. Finally, option D (both a and b) is incorrect because only option A is true.
