When there is no relationship between the co-variables, the correlation is called?

• A. Zero Correlation
• B. Positive Correlation
• C. Negative Correlation
• D. Co-Variables

Answer: (A)

The main idea is how correlation reflects a linear relationship between two variables. When there’s no consistent pattern in how they vary together, the linear association is essentially zero. The correlation coefficient (r) would be around zero, and we describe this as zero correlation. It means there isn’t a linear tendency for one variable to increase or decrease with the other, though there could still be a non-linear or more complex relationship that a simple linear measure wouldn’t capture. A positive correlation would show both variables rising together, a negative one would show one rising as the other falls, and co-variables just refers to the variables themselves rather than a specific relationship.
