. Write the formula of mean deviation method


Best Answer

Mean deviation is used to compute how far the values in a data set are from the middle point. Mean, median, and mode all form middle points of the data set. In different words, the mean deviation is used to calculate the average of the absolute deviations of the data from the central point. Mean deviation may be calculated for each grouped and ungrouped data.
