Solution

The correct option is A 2.32
Total Frequency, N=fi=44.
Mean, u=(fi×xi)N=33044=7.5
xi35791113
fi6815384
C.F61429324044

Thus N=44, even.
M=22nd+23rd2 observations.
M=7+72=7
Now deviations fi×|xiM| are,
|xiM|420246
fi6815384
fi×|xiM|
2416063224

MD(M)=(fi×|xiM|)N=10244=2.32
Thus, MD(M)=2.32
Ans-Option A.
