<PRE><B>Question 700944</B>
&lt;br&gt;&lt;font face=&quot;Tahoma&quot;&gt;I believe this would definitely be an experimental study.&lt;br&gt;

The reason is that the researchers would be directly influencing the subjects,&lt;br&gt;

and then sorting them into non-random groups.&lt;br&gt;

Observational studies on the other hand,&lt;br&gt;

never directly influence the subjects.&lt;br&gt;

Researchers just observe what is already happening in nature, or in the field, and even in the laboratory.&lt;br&gt;

Experimental studies can have huge ethical implications, especially when the subjects are humans or animals.&lt;br&gt;

I hope this helps!  Keep practicing!  :)&lt;br&gt;
