ashley collects data on the number of minutes students ride the school bus before getting to school. 10, 11, 13, 18, 19, 21, 22, 25, 27, 30, 32 find the median of the data set. median: minutes
Answer
Explanation:
Step1: Check number of data points
The data set is 10, 11, 13, 18, 19, 21, 22, 25, 27, 30, 32. There are $n = 11$ data - points.
Step2: Use median formula for odd - numbered data set
For a data set with $n$ data - points (where $n$ is odd), the median is the $\left(\frac{n + 1}{2}\right)$-th value when the data is arranged in ascending order. Here, $\frac{n+1}{2}=\frac{11 + 1}{2}=6$.
Step3: Identify the median value
The 6th value in the ordered data set 10, 11, 13, 18, 19, 21, 22, 25, 27, 30, 32 is 21.
Answer:
21
