The heights in inches of 14 randomly selected adult males in LA are listed as:
71, 67, 70, 59, 71, 68, 67, 71, 80, 68, 74, 69, 72, 68
Display the data in a stem and leaf plot. find the mean, median, mode, range, variance, and standard deviation.

Statistics 
PsyDAG,
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.
