Mean Deviation About Mode For Grouped Data. Mean absolute deviation for grouped data let x i f i i 1 2 n be given frequency distribution. For grouped data we cannot find the exact mean median and mode we can only give estimates.

For grouped data we cannot find the exact mean median and mode we can only give estimates. To estimate the mean use the midpoints of the class intervals. So before calculating mean deviation we need to calculate mean or median according to the need of the problem. The mean of x is denoted by x and is given by x 1 n i 1 n f i x i.
