The stem-and- leaf plot shows the ages of a group of friends. Find the median age. Stem 2 leaf 8, stem 3 leaf 124, stem 4 leaf 279 and stem 5 leaf 4. Key: 2/8=28 years.
Wrong
To find the median age, we first need to list all the individual ages:
28, 31, 32, 34, 37, 39, 41, 44, 44, 44, 47, 49, 54
There are 13 ages in total, so the median age will be the middle value when the ages are listed in numerical order.
Arranging the ages in order, we have: 28, 31, 32, 34, 37, 39, 41, 44, 44, 44, 47, 49, 54
Since there are 13 ages, the median will be the 7th value when listed in numerical order.
Therefore, the median age is 41 years.
