This is a really interesting question because the answer is highly disputed. Obviously Australia doesn't have the economic strength of Europe or the North American Free Trade Agreement, but between the two, it can be measured in different ways, many people would suggest that EU is in fact bigger, but by measure of GDP, the EU is dominated by NAFTA with a per capita GDP of just over $21k in comparison to EU28's which is just over $18k
I would suggest that it is NAFTA at the moment but this answer might be subject to change in the future,
the internal validity is still manipulated by the researcher and the DV is measured.
The DV is a variable that is being measured/observed, whereas the IV is a variable that is altered to see how it impacts something else. The term "dependent" refers to the idea that the IV will have an impact on the DV.
<h3>What parallels exist between studies conducted in a lab and those conducted in the field?</h3>
Since experiments are the only way to reliably establish causality, laboratory and field experiments are comparable in that they are both helpful in determining cause and effect. Furthermore, because there is a high level of control over confounding variables, the two experiment designs have the potential to have high internal validity.
