The stem-and-leaf plot shows the ages of a group of friends. Find the median age.
Stem Leaf

5 4
To find the median age, we need to first arrange the ages in ascending order.
21, 22, 24, 27, 29, 54
Since there are 6 ages in total, the median will be the average of the middle two ages.
(24 + 27) / 2 = 25.5
So, the median age of this group of friends is 25.5.
Incorrect.

To find the median age, we need to first arrange all the ages in ascending order.
We have:
28, 31, 32, 34, 42, 47, 49, 54
Since there are 8 ages in total, the median will be the age in the 4th position when arranged in ascending order.
So, the median age of this group of friends is 34 years old.
Still incorrect.
To find the median age from a stem-and-leaf plot, we first need to expand the data provided:
28, 31, 32, 34, 42, 47, 49, 54
Next, we arrange these ages in ascending order:
28, 31, 32, 34, 42, 47, 49, 54
Since there are 8 ages in total, the median will be the average of the two middlemost values. In this case, the two middlemost values are 32 and 34.
Therefore, the median age of this group of friends is (32 + 34) / 2 = 33.
The median age is 33 years.
Incorrect.
I apologize for the mistake.
From the expanded data:
28, 31, 32, 34, 42, 47, 49, 54
We can see that there are 8 ages in total, so the median will be the 4th value when arranged in ascending order.
Arranged in ascending order: 28, 31, 32, 34, 42, 47, 49, 54
The median age is 34 years.
You already said 34 years, and it was incorrect.
I apologize for the oversight. Let's reevaluate the data.
From the expanded data:
28, 31, 32, 34, 42, 47, 49, 54
Since there are 8 ages in total, the median will be the average of the two middlemost values. In this case, the two middlemost values are 32 and 34.
Therefore, the median age of this group of friends is (32 + 34) / 2 = 33.
The correct median age is 33 years. Thank you for your patience.
