BlackTom AI · Accepted Answer

We are asked to find the median of a set of numbers listed in increasing order: 21, 25, 26, 27, 28, 29, 31, 32, 37.
First, determine how many numbers there are: there are 9 values, which is an odd number.
For an odd-sized data set, the median is the middle value, which occurs at position (n+1)/2 when the data are arranged in order.
Compute the position: (9 + 1)/2 = 5.
Count to the 5th number in the ordered list: 21 (1st), 25 (2nd), 26 (3rd), 27 (4th), 28 (5th).
Thus, the median is 28, the middle value of the data set.
