Question

The graph shown below describes the change in the average temperature of the world over time Degrees above 13 Celsius) 8 15 35 Years since 1970 Negative linear association Nonlinear association No association Positive linear association

Answer 1

Positive Linear Association.

1) Examining that graph we can see that as time goes by the temperature goes rising, not in an exact way as it is described.

2) So we can sketch out something like this:

So we can see an increasing slope. So we can state that this is a Positive Linear association/correlation.

3) Hence, the answer is Positive Linear Association.
