Quizplus · Accepted Answer

The mean is calculated by adding all the scores together and dividing by the number of scores: (71 + 68 + 66 + 65 + 74 + 70) / 6 = 414 / 6 = 69. The median, when the scores are arranged in order (65, 66, 68, 70, 71, 74), is the average of the middle two numbers (68 and 70), which is 69. There is no mode because no score appears more than once.
