(a) Mean score:
Calculate the sum of all scores: 73 + 83 + 72 + 71 + 65 + 70 + 76 + 73 + 83 + 73 = 650
Divide the sum by the number of scores (10): 650 / 10 = 65

Mean score = 65

(b) Median score:
Organize the scores in order: 65, 70, 71, 72, 73, 73, 73, 76, 83, 83
There are 10 scores total. The median will be the 5th number in the ordered list.
Therefore, the median score = 73
