I'm interested in compiling a compendium of truly dysfunctional experimental designs with the goal of making the point of how important it is to involve a statistician from the very initial phases of research. Examples would maximize the (time wasted):(degrees of freedom) ratio. A concrete example would be my 1st undergraduate research project in which I spent an entire summer doing behavioral observations on paperwasps, only to find at the end that I had but 7 dF for my contrasts because I had spent far too much time on each nest, while observing far too few _different_ nests -- which, combined with the variability of data on behavioral observations, no doubt left the power of my comparisons groping asymptotically toward nil. The only positive result of the study was that the following semester I __very eagerly__ started taking statistics courses!! I'll compile the list of horrors and post it here in a couple of weeks so all can use the completed document.
