Mode is most frequently occurring score.
For median, arrange in order of value and choose middlemost value.
Range is highestlowest values.
To find the mean, sum 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.
