They 1) have measured 16,000 neutrinos and found each one above c, or 2) they run the experiment 16,000 times, each run consisting of many measurements, and found that each run produced the result, or 3) they measured 16,000 neutrinos, analysed the data once and found that on average the velocity is higher than c, with 6σ significance?

Yeah, it’s more complicated than all of those but (3) is the closest.
That doesn’t exhaust all possibilities, though it seems to have been 3).
