We measure the strength of the link between two statistical variables using the correlation coefficient. Here are the values of the correlation coefficient of some relations: 0.9, 0.45, -0.95, and - 0.77We want to classify these relationships according to the strength of their correlation, from the strongest to the weakest, which of these classifications is correct?A) -0.95, -0.77, 0.45, 0.9B) 0.9, 0.45,-0.77, -0.95 C) -0.95, 0.9, -0.77, 0.45D) 0.45,-0.77, 0.9, -0.95

Answer:

B) 0.9, 0.45, -0.77, -0.95

Step-by-step explanation:

The correlation coefficient is a statistical measure that indicates the strength of the relationship between two variables. The value usually ranges from -1 to 1 where:

• 1 indicates a strong positive relationship.

,

• -1 indicates a strong negative relationship.

,

• A result of 0 indicates no relationship at all.

Therefore, the given correlation coefficients classified from the strongest to the weakest is:


0.9,0.45,-0.77\text{ and -0.95}

The correct choice is B.
