alleryWhat is the median of 15, 20, 10, 25, 30 and 5?
A15
B17.5
C20
D22.5
Answer & Solution
Correct answer: B. 17.5
1. Order the values: 5, 10, 15, 20, 25, 30.
2. Six values give two middle ones, 15 and 20.
3. Median = (15 + 20) / 2 = 17.5.
15 and 20 are only one of the pair, and 22.5 is the mean of 20 and 25.
