The problem with any of these situations is that the traditional linear regression that might normally be employed in the analysis may produce inconsistent or biased estimates, which is where instrumental variables (IV) would then be used and the second definition of instrumental variables becomes more important. There were 6 instruments we learned on, and each group started on a different one, so some of us were starting the lab on the very last instrument taught about in lecture, and some with the first instrument taught about in lecture...it was incredibly inequitable as a learning environment that some students had the advantage of the lab and lecture being on the same instrument and others the disadvantage of starting with something they knew nothing about based on lecture material.
