What is the median age of the following numbers: 17, 18, 20, 20, 20, 21, 22, 23, 23, 25, 26, 28, 29, 32, 33, 35, 36, 38, 40, and 43
The median age is the middle number when the numbers are arranged in order.
17, 18, 20, 20, 20, 21, 22, 23, 23, 25, 26, 28, 29, 32, 33, 35, 36, 38, 40, 43
Since there are 20 numbers, the median would be the average of the 10th and 11th numbers when arranged in order.
The 10th number is 25 and the 11th number is 26.
Therefore, the median age is (25 + 26) / 2 = 25.5.
Therefore, the median age is 25.5.
