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

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.
