What statistical range indicates no correlation?

• A. -1.00
• B. +1.00
• C. 0.00
• D. -0.50

Answer: (C)

A statistical range of 0.00 indicates no correlation between two variables. In the context of correlation coefficients, a value of 0 signifies that there is no linear relationship between the variables being analyzed. This means that changes in one variable do not predict or influence changes in another variable. In contrast, values of -1.00 and +1.00 represent perfect negative and positive correlations, respectively, where the variables are perfectly inversely or directly related. A value of -0.50 indicates a moderate negative correlation, suggesting that as one variable decreases, the other tends to increase, but not in a perfect manner. Thus, knowing that 0.00 explicitly denotes a lack of correlation is crucial in interpreting statistical data effectively.
