Statistics is exact in a similar way mathematics is . What is inexact is approximation of statistical models and reality . Like you mentioned when testing normality we often say it ' s close enough . But if you then use the normal distribution all the calculations will be exact . Mathematics has the same problem . When you calculate the area of your pizza using pi and radius don ' t you assume that the pizza is a perfect circle ? Well it isn ' t . Your assumption is not exact , but your calculation is . <| sep |> Yeah , I ' ve been really happy with mine . Only problems have been with stuff that doesn ' t properly utilize all the cores . 18 th of an 8350 is not a lot of power it turns out . <| sep |> It comes up every time there is something with accents . So do foreigners dig American accents and everyone is just like errrrrr no .
