To find the median age, we need to arrange the ages in numerical order.
1, 2, 2, 7, 8, 9, 12, 14, 24, 27, 28, 29, 34
There are a total of 13 ages, so the median will be the middle value when the ages are arranged in numerical order. In this case, the median age is the 7th value, which is 12.
Therefore, the median age of the group of friends is 12 years old.
