  1. I 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:

    I hope this helps. Thanks for asking.
