  • If youre unsure about what type of standard deviation you need; either population or sample, check out this link and it explains all (but first read the exam question as it will geerally tell you which one to calculate!):

    Thank you so much Ginger man, you have done in 4:29 minutes what our university lecturer has failed to teach us in 4 months. Love you x

    why cant teachers teach as well as you. It took me a few minutes to understand this, yet it took me 2 hours to understand what the teacher was saying in school and even then i still did not full understand it.
    good job

    I can not be more thankful for this. I was in a lecture and the teacher was going through this on her calculator and I was sitting there like a lost lamb until I came across your video and quickly watched it. Thank you so much!

    My uni couldn’t teach me this, but a man on the internet has done it in 4 minutes. A 4 minute long 8 year old video, has just taught me more than my university did in a whole year.

    Very nice step-by-step instructions. One correction though, "VAR" on the calculator is an abbreviation for "variable", not "variance". If you want to calculate the variance, just square the standard deviation.
