    Variation

    Im having a problem with this. If i have the mean and standard deviation, how do i find the variation? And then how do I find the SD of two diff things with the mean and SD?
    Can someone please explain this to me?

    Variation? Do you mean variance? The variance is the square of standard deviation.

    And then how do I find the SD of two diff things with the mean and SD?
    This also does not make any sense, try rewording closer to the actual problems wording
