The consumption of printing paper reams for the first 11 months of a computer operator is given as 21, 25, 30, 15, 17, 35, 28, 19, 42, 49, and 59. Find the median.
28
Arranging the data in ascending order: 15, 17, 19, 21, 25, 28, 30, 35, 42, 49, 59.
Since there are 11 (odd number of) observations, the median is the \(\dfrac{11+1}{2} = 6^{th}\) value.
The 6th value in the ordered list is 28.
Hence, the median of the given data is 28.
