Respuesta :
A correlation coefficient of 1 or +1 means we have perfect positive correlation. Every point on the scatter plot falls on the same straight line. This straight line has some positive slope. By "positive slope", I mean the line moves upward as you read from left to right. The correlation coefficient r is between -1 and 1 (inclusive). If r = -1, then we have perfect negative correlation. If r is closer to 0, then we have little to no linear correlation at all, which would mean the points are randomly scattered about or they might fall closer to a parabola or some other curve.
Answer: Choice B) Perfect postive correlation
