want to compute the th percentilewhich gives me the point at which of the data is less than that value we can easily do that with the following codeoqqfsdfoujmf wbmthere is the output of that code vu the th percentile of this data turns out to be so it' around hereand basicallyat that point less than of the data is less than that value can believe that of the data is greater than of itless than let' compute the th percentile valuethat would give me the point at which of the values are less than that number that come up with againwe just need very simple alteration to the codeoqqfsdfoujmf wbmtthis gives the following output vu the th percentile point works out to be - roughlyand again believe that it' saying that of the data lies to the left of - and conversely is greater if you want to get feel as to where those breaking points are in datasetthe percentile function is an easy way to compute them if this were dataset representing income distributionwe could just call oqqfsdfoujmf wbmtand figure out what the th percentile is you could figure out who those one-percenters people keep talking about really areand if you're one of them alrightnow to get your hands dirty want you to play around with this data this is an ipython notebook for reasonso you can mess with it and mess with the codetry different standard deviation valuessee what effect it has on the shape of the data and where those percentiles end up lyingfor example try using smaller dataset sizes and add little bit more random variation in the thing just get comfortable with itplay around with itand find you can actually do this stuff and write some real code that works
