Median Formula for Grouped Data
Calculate the mean deviation for grouped data. Standard Deviation simply stated is the measure of the dispersion of a group of data from its meanIn other words it measures how much the observations differ from the central mean.

When the data is continuous and in the form of a frequency distribution the median is calculated through the following sequence of steps. Estimated Median L n2 BG w. And if n is even then the median will be the average of the n2th and the n2 1th observation. Then if n is odd the median is the n12. To find this deviation in an ungrouped data is not that complicated but to calculate the mean absolute deviation in grouped data is a little more complex because we have to do more steps.
