The median of the data 205, 170, 131, 174, 153, 142, 148, 157, 196, 148 is:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 155
The median is the middle value once the data is arranged in order. With an even number of values there are two middle values, and the median is their average.
In ascending order: 131, 142, 148, 148, 153, 157, 170, 174, 196, 205
There are 10 values, so the middle ones are the 5th and 6th: 153 and 157
Median \(\displaystyle =\frac{153+157}{2}=155\)
