Right Answer is: A
SOLUTION
Concept:
Mean = Sum of all observation/number of observations
Mode = Maximum frequency
Median = [(n + 1)/2]th, if n = odd number
Analysis:
Arranging the data in increasing order, we get the distribution as:
6, 7, 8, 9, 9, 10, 12, 15, 15, 22
The maximum occurring terms are 9 and 15.
∴The mode of the data is 9 and 15
