Answer:

【Answer】: 9. a

12. d

【Explanation】: 9. The data provided is a list of individual scores, which means it is not grouped into intervals or categories. Therefore, it is ungrouped data.

12. The range of a set of data is the difference between the highest and lowest values. In this case, the highest score is 21 and the lowest score is 15. The difference between these two values is \(21 - 15 = 6\).
