analyzing standard deviation and variance on histogram let' write some code here and play with some standard deviation and variances so if you pull up the ue%fw bsjbodfjqzoc file ipython notebookand follow along with me here please dobecause there' an activity at the end that want you to try what we're going to do here is just like the previous exampleso begin with the following codenbuqmpumjcjomjof jnqpsuovnqzbtoq jnqpsunbuqmpumjcqzqmpubtqmu jodpnft oqsboepnopsnbm qmuijtu jodpnftqmutipx we use nbuqmpumjc to plot histogram of some normally distributed random dataand we call it jodpnft we're saying it' going to be centered around (hopefully that' an hourly rate or something and not annualor some weird denomination)with standard deviation of and data points let' go ahead and generate that by executing that above code block and plotting it as shown in the following graph
