Answer:
Min = 0; Q₁ = 0; Median = 2; Q₃ = 2; Max = 8
Step-by-step explanation:
Assume that your sorted data are
0, 0, 0, 0, 0, 0, 0, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 3, 3, 3, 3, 4, 5, 8
1. Minimum
Min = 0
2. Median
The median is the middle value in a sorted data set. There are 25 items, so the median is the 13th item.
Median = 2
3. First quartile
Q₁ is the median of the lower half of the data set.
The median of 0, 0, 0, 0, 0, 0, 0, 1, 1, 1, 1, 2 is 0.
Q₁ = 0
4. Third quartile
Q₃ is the median of the upper half of the data set.
The median of 2, 2, 2, 2, 2, 3, 3, 3, 3, 4, 5, 8 is 3.
Q₃ = 3
5. Maximum
Max = 8
