Which of the following correlation coefficients expresses the weakest degree of relationship between two variables? a.) 0.10 b.) -0.12 c.) -0.99 d.) +0.25

The correlation coefficient between the variables are always between +1 and -1

If the correlation coefficient is near to +1 the degree of relationship between variables is strongly positively correlated. And if the correlation coefficient is near to -1 the degree of relationship between variables is strongly negatively correlated.

Hence at the extremes +1 and -1, there is a strong degree of relationship between two variables

Near to 0 (the middle of the range), there is a weak degree of relationship between two variables

So, the answer would the value the is nearest to 0 since we want a weak relationship

The value that is nearest to 0 is a) 0.10

So, the answer is a)0.10

0.10
