A dataset has values: 5, 8, 12, 14, 17, 21, 25, 29. What is the median of this dataset?
Answer and explanation
Correct answer: B. 15.5
- Step 1: Count observations n = 8 (even number).
- Step 2: Identify the two middle terms: 4th term = 14, 5th term = 17.
- Step 3: Compute the average of the two middle terms: (14 + 17) / 2 = 31 / 2 = 15.5.
Answer
15.5.
Why not the others: Option 14.0 takes only the 4th term. Option 17.0 takes only the 5th term. Option 16.0 rounds 15.5 to the nearest whole integer.
