Question

a crayon factory monitored the number of broken crayons per box during the past day.
broken crayons per box
stem | leaf
5 | 9
6 | 7 9
7 | 2 3 3 4 5 9
8 | 1 3
what is the median of the numbers?

Explanation:

Step1: List all data values

From the stem-and-leaf plot, the data is: 59, 67, 69, 72, 73, 73, 74, 75, 79, 81, 83

Step2: Count total data points

There are $n=11$ values.

Step3: Find median position

For odd $n$, median position is $\frac{n+1}{2} = \frac{11+1}{2}=6$

Step4: Identify 6th ordered value

The 6th value in the sorted list is 73.

Answer:

73
