Find all median of the numbers 89, 141, 130, 161, 120, 131, 131, 100, 108 and 119
A
131
B
125
C
123
D
120
correct option: b
To find the median, we first arrange in ascending order:
89, 100, 108, 119, 120,130, 131, 131, 141, 161
Since there are even number of items, we take the avarage of the two middle items:
Median = \(\frac{120 + 130}{2}\) = 125
