Median: To find the median, we need to first arrange the data in numerical order. The scores are 60, 60, 66, 70, 70, 74, 77, 77, 80, 80, 84, 89. There are 12 scores in total, so the median is the average of the 6th and 7th scores, which are both 74. Therefore, the median is 74.
Mode: The mode is the value(s) that appears most frequently in the data set. In this case, the mode is 70 because it appears 3 times, whereas all other scores appear only once.
Range: The range is the difference between the highest and lowest values in the data set. The highest value is 89 and the lowest value is 60. Therefore, the range is 89 - 60 = 29.
