What is the median of 4, 2, 7, 3, 10, 9, 13?
A6
B8
C9
D7
Answer:
D. 7
Read Explanation:
Given data: 4, 2, 7, 3, 10, 9, 13 First, arrange the given data in ascending order. I.e., 2, 3, 4, 7, 9, 10, 13 So, the number of observations is 7. (n= 7) Since the number of observations is odd, the median can be calculated as follows: Median = [(n +1)/2]th term Median = [(7 +1)/2]th term Median = [(8)/2]th term Median = 4th term = 7
