Find the median of the data 17, 23, 1, 52, 11, 11, 31, 34, 26, 9, 56, 64, 2, 1.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 20
The median is the middle value after arranging the data in order. With an even number of values, it is the average of the two middle values.
In ascending order: 1, 1, 2, 9, 11, 11, 17, 23, 26, 31, 34, 52, 56, 64
There are 14 values, so the middle values are the 7th and the 8th: 17 and 23
Median \(\displaystyle=\frac{17+23}{2}=20\)
The median is 20.
