When calculating the median absolute deviation (MAD) via fun.data = median_mad using the function stat_summary in ggplot2, the constant factor is set to 1.4826 by default. However, I want to s et the constant factor to 1 in the stat_summary function.

Regarding the difference between mean absolute deviation & standard deviation the both involve the deviation of ALL the points from the mean. One involves the sum of the absolute deviations from the mean while the is the square root if the sum of the squared deviation.. $\endgroup$ – Michael R. Chernick Sep 18 '19 at 21:14

The value 1.4826 is not numerically precise for scaling with a normal distribution. A measure used to find how much the values in a data set vary from their mean is called as the mean absolute deviation. It is also termed as mean deviation or average absolute deviation. It can be calculated by finding the mean of the values first and then find the difference between each value and the mean. This video demonstrates how to calculate the median deviation (median absolute deviation) using SPSS.

Written by Peter Rosenmai on 25 Nov 2013. Last revised 13 Jan 2013. One of the commonest ways of finding outliers in one-dimensional data is to mark as a potential outlier any point that is more than two standard deviations, say, from the mean (I am referring to sample means and standard deviations here and in what follows). Median Absolute Deviation (MAD) or Absolute Deviation Around the Median as stated in the title, is a robust measure of central tendency.
