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

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.
