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

Mode = most frequently occurring score

Once arranged in order of value, the median = 50th percentile.

Range = highest score - lowest

I'll let you do the calculations.
