Which association has slope -1?

Which figure gives perfect linear correlation?

When the value of the independent variable increases and the value of the dependent variable
Increases such type of correlation is

When the value of the independent variable increases and the value of the dependent variable
decreases such type of correlation is

The correct option is (a).
Reason : Whenever there is decrease in dependent variable with increase in independent the graph is downward with negative slope

When the value of the independent variable increases and the value of the dependent variable
decreases such type of correlation is

The correct option is (a).
Reason : Whenever there is decrease in dependent variable with increase in independent the graph is downward with negative slope

The scatter plot shows David’s height at various ages. Choose the right answer that describe the type of association between David’s age and his height.

The corerect option is (c)
Reason :
As the height of David increases with increase in his age , the graph is going upward as both the variable are increasing so it is a case of positive association and since there is almost constant change in both the variable it is shows linear relationship also

The scatter plot shows David’s height at various ages. Choose the right answer that describe the type of association between David’s age and his height.
