Mean of Ungrouped data

barx=A+(sumf_i d_i)/(sumf_i) is the formula to find mean for an ungrouped data. In this formula letter A represents for

Mean Deviation (Mean deviation for ungrouped data or Individual Responses) Explain with some examples

The mean of the ungrouped data is given by

The coefficient of variation and standard deviation of an ungrouped data are 60 and 21 respectively. If 15 is added to every observation of the data, then the coefficient of variation of the new data is
