A) 9
B) 10.5
C) 12.67
D) 14.76
Correct Answer: C
Solution :
[c] Marks obtained by 9 students in Mathematics are: 50, 69, 20, 33, 53, 39, 40, 65, 59 Let us rewrite the given data in ascending order. 20, 33, 39, 40, 50, 53, 59, 65, 69, Here, n = 9 Median \[({{M}_{e}})\]= 5th term=50\[{{x}_{i}}\] | \[{{d}_{i}}=\left| {{x}_{i}}-{{M}_{e}} \right|\] |
20 | 30 |
33 | 17 |
39 | 11 |
40 | 10 |
50 | 0 |
53 | 3 |
59 | 9 |
65 | 15 |
69 | 19 |
N=2 | \[\Sigma \,{{d}_{1}}=114\] |
