    @MarkFL give me the average percentage out of these:

    63%
    25%
    33.3%
    62%
    45.8%
    25%

    And then the average out of these percentages:

    53.8%
    35.3%
    27.8%
    50.7%
    56.5%
    66.7%

    Cba to figure it out myself, I'm tutoring chess and these are best move percentages across 6 of their games. Want to find out what the average was.

    In words, that formula tells you that to find the arithmetic mean (average - denoted by x-bar), add up the numbers, then divide the resulting sum by the number of numbers (which I assume you did). :)

    Oh, I thought you were mocking me by posting some complex formula.

    I will admit that I was trying to be a little "math nerdy" but not mockery was intended. :)

    No, I assure you it simply states how to compute the mean of a set of numbers. Mathematics is meant to be useful, not derisive. :)
