, |Xn − X tilde|}/0.6745 can Jun 16, 2016 Any observation from the distribution has a 0.5 probability of being within plus or minus 0.6745 of the median. Therefore, instead of MAD, Q.D.= 0.6745 , then = Q.D. /0.6745 = 3.3725/0.6745 = 5. 14- What is the relationship between mean, median and mode in a normal distribution? multiplied by 0.6745 and divided by the median absolute difference for the set [ 37 ] . Then, if the largest gene-expression value in a given set of six values had the median, and the rest of the data as ordinary least squares does, we must Our "standard deviation", H, is given by: median | y; - median (;). 0.6745.
