a random sample of 200 men aged between 20 and 60 was selected from a certain city. The linear correlation between inome and vlood pressue was found to be r=0.087

What does this imply?

does this suggest that if a man gets a salary raise his blood pressue is likely to rise?

what are likely lurking variables?

Solution

Since correlation coeffcient between the variables is 0.087 so it shows a very weak and positive relationship between the variables. On the basis of correlation coeffcient we can suggest that there is very little chance that  if a man gets a salary raise his blood pressue is likely to rise.

Lukring variables: May be person have some health issue and he/she was taking medicines for blood pressure.
