Correct option is (1).

Step-by-step explanation:

A linear relationship between two variable, an independent and dependent variable is represented by a straight line.

Any change in the independent variable leads to a change in the dependent variable.

The degree of association between two variable is measure by the correlation coefficient.

The correlation coefficient value ranges from -1.00 to 1.00.

A correlation value of 1.00 implies a strong positive relation between the variables and a correlation value of -1.00 implies a strong negative relation between the variables.

The correlation between two variables only tells us about the degree and direction of the relationship between two variables.

It does not implies causation, i.e. it does not tells whether the changes in the dependent variables are due to the independent variables or some other factor.

Thus, the correct option is (1).
