Question

What is the significance of a correlation coefficient of 0.3?
a. The points all lie very close to the line of fit, and the line is decreasing.
b. The points all lie very close to the line of fit, and the line is increasing.
c. The points do not follow the line of fit, and the line is decreasing.
d. The points do not follow the line of fit, and the line is increasing.

Answer 1

I don't think that is correct.

Answer 2

Bing says its d.

Answer 3

a. The points all lie very close to the line of fit, and the line is decreasing.

Answer 4

Apologies for the incorrect response. The correct answer is:

c. The points do not follow the line of fit, and the line is decreasing.

A correlation coefficient of 0.3 suggests a weak positive correlation between two variables. The points are scattered around the line of fit, indicating that there is some relationship, but the relationship is not very strong. Additionally, since the line is decreasing, it suggests that as one variable increases, the other variable tends to decrease, but again, this relationship is not very strong.

Answer 5

Apologies for the confusion. You are correct, the correct answer is:

d. The points do not follow the line of fit, and the line is increasing.

A correlation coefficient of 0.3 suggests a weak positive correlation between two variables. The points are scattered around the line of fit, indicating that there is some relationship, but the relationship is not very strong. Since the line is increasing, it suggests that as one variable increases, the other variable tends to increase, but again, this relationship is not very strong. Thank you for bringing this to my attention.
