    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!

    You saved my life buddy. You pulled your hair trying to figure this out? I almost scalped mine. Well done for figuring it out and thanks for sharing this. You saved my life (
    and my scalp).

    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.

    I think you use the mid point for the x values and then use the frequency as you described, then use the population standard deviation from the stat(var) menu. Right?
