Answer 1

Using the list exactly as written (with two entries of 1313):

- Mean = 2979 ÷ 25 = 119.16
- Median = 14 (13th value in the ordered list)
- Mode = 13 (occurs 8 times)
- Range = 1313 − 13 = 1300

Note: If the two "1313" entries are typos for "13", then the mean becomes 379 ÷ 25 = 15.16, the median is 14, the mode is 13, and the range is 21 − 13 = 8.
