What is the median of the following set of data: 11, 12, 18, 14, 22, 17, 17, 12, 26, 12, 13?
Correct answer
B
Rationale
To find the median of a set of data, first arrange the numbers in ascending order: 11, 12, 12, 12, 13, 14, 17, 17, 18, 22, 26. Since there are 11 numbers in the set, the median will be the middle value. When arranged in ascending order, the middle value is 14, which makes it the median of the data set. Therefore, the correct answer is 14.
