Solution

The correct option is D $M = M_{g}$
Mean of ungrouped data or raw data= $M = ¯ x = \frac{\sum x}{n}$
And mean of grouped data= $M_{g} = ¯ x = \frac{\sum x}{n}$
Then $M = M_{g}$

If M and Mg represents the mean of the raw and grouped data respectively then

The correct option is D M=MgMean of ungrouped data or raw data=M=¯x=∑xnAnd mean of grouped data=Mg=¯x=∑xnThen M=Mg

If M and $M_{g}$ represents the mean of the raw and grouped data respectively then

The correct option is D $M = M_{g}$
Mean of ungrouped data or raw data= $M = ¯ x = \frac{\sum x}{n}$
And mean of grouped data= $M_{g} = ¯ x = \frac{\sum x}{n}$
Then $M = M_{g}$
