The weights (in kg) of 9 parcels are 83, 76, 91, 68, 88, 72, 95, 79, 64. Find the median weight.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 79
For an odd number of values, the median is the middle value after arranging them in order. With 9 values, it is the 5th value.
In ascending order: 64, 68, 72, 76, 79, 83, 88, 91, 95
The 5th value is 79
The median is 79.
Why the other options are incorrect
Option (1) 88 — Incorrect. This is the middle value of the list as written; the values must first be put in order.
Option (3) 83 — Incorrect. This is the 6th value in order, one place after the middle.
Option (4) 76 — Incorrect. This is the 4th value in order, one place before the middle.
