alleryWhat is the median of the ten values 2, 4, 6, 8, 10, 12, 14, 16, 18 and 20?
A10
B20
C12
D11
Answer & Solution
Correct answer: D. 11
1. The list is already in order and has 10 values.
2. The two middle values are the 5th and 6th: 10 and 12.
3. Median = (10 + 12) / 2 = 11.
10 and 12 are only one of the middle pair, and 20 is the last value.
