Answer 1

Answer: D . No association

Step-by-step explanation:

The relationship between two variable is called correlation.

• When two variables has positive correlation ( When one variable increases by increasing the other) then it reprsesents Positive linear association .
• When two variables has negative correlation ( When one variable decreases by increasing the other) then it reprsesents Negative linear association .
• When two variables in which change in one variable does not correspond with constant change in the other variable, then it represents Nonlinear association.
• If two variables are not interdependent such that if one increasing then there is no proportional change in the other variable, then we say there is no correlation.

Hence, the correct option is D. No association.
