Question

Which correlation coefficient represents a moderate negative correlation? a.r = –0.04 b. r = –0.24 c.r = –0.64d. r = –0.94

Answer 1

Answer: r = -0.64

Step-by-step explanation:

The correlation coefficient is a measure of the strength of the linear relationship between two variables and is denoted by r. Values between 0.3 and 0.7 indicate a moderate positive (negative) linear relationship .

Values between -0.3 and -0.7 indicate a moderate negative linear relationship .

The only value of r in the option is r= -0.64 lies in given interval of moderate negative linear relationship .

Therefore, c is the right answer.

Answer 2

I believe the correct answer from the choices listed above is option C. It would be r = –0.64 that represents a moderate negative correlation. It is a is a relationship between two variables in which one variable increases as the other decreases, and vice versa. Hope this answers the question. Have a nice day.
