here are the ages of 13 people in a coffee shop on a given day: 26, 44, 22, 28, 55, 32, 15, 39, 54, 69, 21, 18, 48. identify the median according to the data arranged from least to greatest. 15, 18, 21, 22, 26, 28, ?, 39, 44, 48, 54, 55,
Answer
Explanation:
Step1: Recall median formula
For a set of $n$ data - points arranged in ascending order, if $n$ is odd, the median is the $\left(\frac{n + 1}{2}\right)$-th value. Here $n=13$.
Step2: Calculate the position of the median
$\frac{n + 1}{2}=\frac{13+1}{2}=7$.
Step3: Find the median
The 7 - th value in the ordered data set $15,18,21,22,26,28,32,39,44,48,54,55,69$ is $32$.
Answer:
$32$
