A, B, C are three sets of values of x:
A: 2, 3, 7, 1, 3, 2, 3
B: 7, 5, 9, 12, 5, 3, 8
C: 4, 4, 11, 7, 2, 3, 4
Which one of the following statements is correct?
A: 2, 3, 7, 1, 3, 2, 3
A: 1, 2, 2, 3, 3, 3, 7
Mode = 3 (occurs maximum number of times)
Median = 3 (the middle term)
Mean = 
= 
= 3
Hence, option (d) is true.
