There is a possibility I will be hired to work as a statistical analyst on an NSF grant. Statistically it's not going to be difficult, I don't think - based on what the student was saying, this sounds like either a t-test or Wilcoxon rank-sum (depending on assumptions), although I reserve the right to run it through Observation Oriented Modeling just for grins/if the assumption violations get too ugly. How would you work up a billing rate? When I've consulted in the past, I've done both an hourly rate and a flat fee, but the stats were a bit more complicated. OTOH, the reason I got called is because the nuts and bolts of it is beyond the student's area of expertise - the study will involve students in his discipline, but the heart of it is (academic) assessment - so I may be sweating out some of the methodology such that we get useful data. Thoughts?
