We do not do your homework for you. Although it might take more effort to do the work on your own, you will profit more from your effort. We will be happy to evaluate your work though.
However, I will start you out.
mean = ∑x/n, where x = score values and n = number of scores.
Median — arrange scores in order of value, then the middle-most score or 50th percentile = median.
Mode = most frequently occurring score.
