Calculating sample

  1. Jan 16, 2005 #1
    I was just wondering, this is a simple question, but i have started intro to stats, lol, but anyways i was wondering what s^2 and s is, like i was given a sample size and some observations. Now i was asked to calculate s^2 and s, how do i do that, and what is s^2 and s?

    s is sample standard deviation and s2 is sample variance. Here's one description: http://www.quickmba.com/stats/standard-deviation/. Computationally, they are only different from the population variance and standard deviaion by their denominators ((N-1) instead of N).
