Final answer:
The correlation coefficient of +1.0 indicates a strong positive linear relationship between two measurement variables. As one variable increases, the other variable also increases.
Step-by-step explanation:
The correlation coefficient between two measurement variables of +1.0 indicates a strong positive linear relationship between the variables. This means that as one variable increases, the other variable also increases. Therefore, the statement that is NOT true is: 1) As one variable increases, the other decreases.
