Question

10) Suppose you were asked to test the proposition that publishing students' teacher evaluations causes grade inflation. What evidence might you want to consider? How would the inability to carry out controlled experiments make your analysis more difficult? (Two paragraphs)

Answer 1

If the students' teacher evaluation causes grade inflation one must be keen on covering the reasons behind this extrapolation and biasedness towards such results. Also one needs to have data as to what mptivates teachers to publish an inflated result or what cost to benefit analysis precedes this event.

The inability and non availability of sufficient data behind this causation and defining hypothesis or taking any form of variables for consideration makes the analysis in cintrolled way very difficult as this may lead to variance as tecahers in a controlled environment may display different behavioural aspects which brings deviation from our purpose of research.
