Here,Nis45,whichisodd.Median={(N+12)thobservation}={45+12}observation=23thobservationMedian=150Mean=∑(fi×xi)∑fi=705045=156.67Mode=3(Median)−2(Mean)=3(150)−2(156.67)=450−313.34=136.6Here,Nis45,whichisodd.Median=N+12thobservation=45+12observation=23thobservationMedian=150Mean=∑(fi×xi)∑fi=705045=156.67Mode=3(Median)-2(Mean)=3150-2(156.67)=450-313.34=136.6

Hence, the median is 150, the mean is 156.67 and the mode is 136.6.
