well i have a question regarding a z-score calculation.
i have an array of values like this:
and a population of such arrays
to calculate a z score i would need to somehow derive a single number from my sample and a mean from my population. but the problem is i'm quite insecure in calculating an average from a single array like:
(23,45,32,12,65,34,67,22) -> avrg == mean =37.5
to get this single number and then doing the same thing for every single outcome in my population. is there an alternative??
how to calculate a z score for such a case ?
this is basically a type of vector manipulation that i'm not very familiar with ..
so what i want to do is to calculate a z-score for my experiment that has a set of outcomes compared to a population of experiments where every exper. in my population is consisted of also a set of outcomes
