Which of the following statements is correct? O Changing the units of measurements of the explanatory or response variable does not change the value of the correlation. A negative value for the correlation indicates that there is no relationship between the two variables. The correlation has the same units (e.g., feet or minutes) as the explanatory variable. O Correlation between y and x has the same number but opposite sign as the correlation between x and y.
