here are 13 of alis walk times to the nearest restroom (in seconds): 26, 34, 15, 62, 89, 71, 23, 13, 32, 54, 52, 50, 21. what is the median?
Answer
Explanation:
Step1: Arrange data in ascending order
$13, 15, 21, 23, 26, 32, 34, 50, 52, 54, 62, 71, 89$
Step2: Find the middle - value
Since there are $n = 13$ data points (an odd number), the median is the $\left(\frac{n + 1}{2}\right)$-th value. $\frac{13+1}{2}=7$ - th value.
Answer:
$34$
