| 11 | 6 | 22 | 7 | 10 | 6 | 15 |
A) Their median is 11.
B) Their mean is 11.
C) Their range is 16.
D) Their mode is 6.
Correct Answer: A
Solution :
Arranging the given data in ascending order, we get, 6, 6, 7, 10, 11, 15, 22 \[mean=\frac{\text{6}+\text{6}+\text{7}+\text{1}0+\text{11}+\text{15}+\text{22}}{7}\] \[=\frac{77}{7}=11\] Mode = 6 Median = 4th value = 10 Range = 22 - 6 = 16
