In this video, Kathryn demonstrates Python's statistics module. Learn how to use this module to compute the mean, mode, median, and standard deviation from a set of values.
- The statistics module allows us…to calculate common statistics…like the mean, mode, standard deviation, et cetera.…But it also allows us to do some more…complicated things as well.…So to start off,…we'll go, import statistics,…to import this module.…And we're going to create some data.…So we're going to start off with agesData as our variable.…And this is going to contain…the ages of people at a given summer camp.…So say the employees at this summer camp want to know…the demographics of who attends.…
Well first you have to have the data.…And so say we have…10, 13, 14, these are just some ages.…I'm putting an 11, 10, 11, 10, 15.…But before we jump in on how we use this module,…let's review some statistics.…So here are some statistic definitions.…We have the mean, median, and mode.…So forget about the code for a minute,…and think about this data.…Say we have 2, 2, 3,…standing for how many cookies each person has.…
We can use statistical methods…to get more information about this data.…And this is where mean, median, mode, come in.…
