Question

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.

  1. The association is positive and basically linear
  2. make predictions
  3. trend of correlation
  4. to connect two points

The correct answer is: The association is positive and basically linear


    As David is getting older, his height increases roughly along a straight line on the graph, so the association is positive and basically linear.

    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
