You could calculate it yourself, but I'm just trying to look at the distributions and get an intuition here. At least in this case, it looks pretty clear that the swimmers had faster times on average in the finals. It took them less time. One of the swimmers was disqualified from the finals. That's not true. We have eight swimmers in the semifinal round and we have eight swimmers in the final round, so that one's not true. The times in the finals vary noticeably more than the times in the semifinals.
