The median age is 35 years.
To find the median, we first need to order the ages from least to greatest:
28, 31, 32, 34, 42, 47, 49, 54
There are 8 ages in total, so the median is the middle value. Since there are an even number of ages, we take the average of the two middle values:
Median = (34 + 42)/2 = 76/2 = 38
So the median age of the group is 38 years.
The stem and leaf plot shows the ages of a group of friends find the median age.
2 | 8
3 | 1 2 4
4 | 2 7 9
5 | 4
Key: 2|8 = 28 years
