(2) The median-based method considers an observation as being outlier if the absolute difference between the observation and the sample median is larger than the Median Absolute Deviation divided by 0.6745. In this case, the central reference line is set at the median, while the other two are set at median-2*MAD/0.6745 and median+2*MAD/0.6745.

Compute the median absolute deviation, i.e., the (lo-/hi-) median of the absolute deviations from the median, and (by default) adjust by a factor for asymptotically normal consistency. Usage mad(x, center = median(x), constant = 1.4826, na.rm = FALSE, low = FALSE, high = FALSE) Arguments r = 0.6745 √ ((v 1 2 + v 2 2 +⋅⋅⋅ ….v n 2) / n-1) Where v 1 , v 2 , v 3 and v 1n are defined as residuals calculated as the difference between a measurement and the mean over a set of measurements. The modified z score is a standardized score that measures outlier strength or how much a particular score differs from the typical score. Using standard deviation units, it approximates the difference of the score from the median. From the box, we can see that the median of the dataset falls at 66.5 inches, and that the first and third quartiles fall at approximately 64 and 70 inches, respectively. The whiskers show us that there are no outliers (as calculated by the IQR method) on the low end, but there is one on the high end, which is defined as over 78.25 inches.
