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

As x increases, y increases. correlation coefficient causation negative correlation positive correlation

The Pearson correlation coefficient between two variables, x and y, based on a random sample, is found to be -0.6.Question 15Which one of the following is always correct?For each increase in x of 10 units, y will reduce by 6 unitsFor each increase in y of 10 units, x will decrease by 6 unitsThere must be some causal factor between x and yIf 10 units were added to each y value the correlation coefficient would not change

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.

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
