  1. Find the mean first = sum of scores/number of scores

    55*1 + 65*309 + 75*1433....

    Subtract each of the scores from the mean and square each difference. Find the sum of these squares. Divide that by the number of scores to get variance.

    Standard deviation = square root of variance

    I'll let you do the calculations.
