 Re: Will Enterprise Ever Learn About Working People So Much
Anyone who has ever taken a good statistics course knows that calling only 30 random customers out the thousands you take care of in a month is a terrible sample size. I seem to remember numbers greater than 120 to be the fairly reliable from one of my old statistics textbooks. Anything less than this produces unreliable results. Thus, whoever ERAC has contracted to conduct ESQI calls is producing data that is statistically about as thin as Calista Flockhart's waistline. Believe or not, there are even mathematical reasons to show that ESQI is useless. |
