 Aha! Statistic! This is surely something important. We named our discipline after these things. So what I know this is statistic. It says here that it is a summary measure computed from a sample. Speak English, Cassie. Okay. It is any way of mushing up the data that I have. So something you might expect me to do if I have measured some tree heights from those trees is to mush up their data, take an average and report to you that their average height is 22.5 meters. Very usual. But you could, if you felt like it, instead take the top three tree heights. I don't know, add them up, take the log add to that, the square root of the difference of the bottom two tree heights. Send the whole thing through a meat grinder. Out pops another statistic. Maybe useful, maybe not so useful. But both are statistics. It's just any way of mushing up the data that we have.
