In all fairness, this is a poll of a very particular sub-population (Crunchbase founders and investors). The entire population is 8499 people, so a sampling size of 3k would be more than a third of the population. The sample size for most questions is 129 (but not random, since those were only the ones who responded). I just found that one graph weird, but admittedly I haven't looked carefully at everything else.
