The following are all quiz scores of a student in a statistics course. Each quiz was graded on a 10-point scale.



10,6,7,6,5,8

Assuming that these scores constitute an entire population, find the standard deviation of the population. Round your answer to at least two decimal places

  • statistics -

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

    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.
