Mathematical existential crisis
27 Mar 2007in my statistics class we are studying hypothesis testing and how to determine if two samples (i.e. pools of data, in this case life expectancy and heights of presidents: i like presidents! i like height! it’s pretty sweet, though they do not include abraham lincoln because his life ended in an early and unfair fashion) are statistically comparable.
having recently completed a problem in which i decided that two variances were close enough to be considered equal, i wondered: at what point did we decide to declare equal things which are NOT equal? 86.9 and 73.6 are not the same, though apparently they can be used this way when making additional calculations.
this is weird, and a little scary. i need more information.
