If an increase in one variable is not associated with any consistent increase or decrease in a second variable , then the correlation between the two variables is _______________________.Group of answer choicesA. PositiveB. NegativeC. ZeroD. Uncertain

If the correlation between variable A and variable B is greater than +1, _____________________________________________.Group of answer choicesA. the mean value of A is greater than the mean value of B.B. either A causes B or B causes A.C. someone calculated the correlation incorrectly.D. A causes B.

It presents that as the value of one measure increases, the value of the other measure decreases.Select one:a.correlation coefficientb.negative correlationc.positive correlationd.zero correlation

As x increases, y decreases. positive correlation negative correlation no correlation correlation coefficient

Assuming a linear relationship between X and Y, if the coefficient of correlation (r) equals – 0.30, A. the variance of X is negative. B. variable X is larger than variable Y.                          C. there is no correlation.                                      D.  the slope (b1) is negative.

The correlation of X with Y is 0.6. This might be explained by:Group of answer choicesAny of the other options are possible explanations.X causes YY causes XX does not cause Y and Y does not cause X
