Since the value 75 is repeated two times, so we have assigned an average rank of 3rd and 4th rank i.e. (3+4)/2= 3.5 each. Similarly, the value 14 is appearing three times, so we have assigned an average rank of 4th, 5th and 6 th ranks i.e. (4+5+6)/3= 5 each.

Therefore, m1 = 2 ( as 75 is repeated two times) and m2 = 3 (as 14 is repeated three times)
