Question

Which of the following correlation coefficients indicates that you could use measurements of one variable to predict measurements of a second variable with perfect accuracy?A)  .9B)  0C)  -1D)  .5

Marie Louise · Accepted Answer

Final Answer : C, Explanation :  A correlation coefficient of -1 indicates a perfect negative correlation, which means that as one variable increases, the other variable decreases in exact proportion. Therefore, if you know the value of one variable, you can predict the value of the other variable with perfect accuracy.
