Find the median for the data 8, 5, 7, 10, 15, 21.
A11
B13
C9
D17
Answer:
C. 9
Read Explanation:
Arranging the given data in ascending order, we get, 5, 7, 8, 10, 15, 21. Here, the number of observations is 6, which is even. Hence, Median = [(n/2)th term + ((n/2) + 1)th term]/2 Median = [(6/2)th term + ((6/2) + 1)th term]/2 Median = (3rd term + 4 term )/2 Here, 3rd term = 8 and 4th term = 10 Therefore, median = (8+10)/2 = 18/2 = 9 Hence, the median of the given data is 9.
