**PsyDAG**, Wednesday, May 7, 2008 at 11:27amI will not find the values for you, but here is how you can get them.

For the mean, add all the scores and divided by the number of scores.

μ = ΣX/N

The mode is the most frequently occurring score.

For the median, first you must arrange the scores in order of their value. The middle-most score is the median.

The range is the highest score minus the lowest.

This should help you with the standard deviation:
