Therefore, the range is 11, the first quartile is 19.5, the third quartile is 26.5, and the quartile deviation is 3.5.

1. Range = 11 Range is the difference between the largest and smallest values in a dataset. In this case, the largest value is 28 and the smallest value is 17, so the range is 28 - 17 = 11.
2. First quartile (Q1) = 19 First quartile is the median of the lower half of the dataset. To find Q1, we first sort the data in ascending order: 17, 19, 20, 23, 24, 26, 27, 28. The median of the lower half is 19, so Q1 is 19.
3. Third quartile (Q3) = 26 Third quartile is the median of the upper half of the dataset. To find Q3, we consider the data from Q1 onwards: 19, 20, 23, 24, 26, 27, 28. The median of this half is 26, so Q3 is 26.
4. Quartile deviation (QD) = 3.5 Quartile deviation is half of the difference between Q3 and Q1. In this case, QD = (26 - 19) / 2 = 3.5.
