Question

the median of the data set 5, 8, 3, 12, 7 is: a. 7 b. 5 c. 9 d. 8

Explanation:

Step1: Sort the data set

Sort \(5,8,3,12,7\) in ascending order: \(3,5,7,8,12\)

Step2: Find the median

For a data set with \(n = 5\) (odd number of elements), the median is the \(\frac{n + 1}{2}\) -th element. \(\frac{5+ 1}{2}=3\) -rd element. The third element in \(3,5,7,8,12\) is \(7\)
