Body voltage testing â also called skin voltage testing â is the most sensitive, accurate and helpful method available to detect electric fields. This is a very important measurement, especially for sensitive individuals.
An outlier can be created by a shift in the location. (mean) or in the scale (variability) of the process. Though an observation in a particular sample might be a. candidate as an outlier, the process might have shifted. Sometimes, the spurious result is a gross recording. error or a measurement error.
How to fix. 1  Itâs possible that this is a measurement or data entry error, where the outlier is just wrong, in which case you should delete it. 2  Itâs possible that what appears to be just a couple outliers is in fact a power distribution. 3  If it is indeed a legitimate outlier, you should assess the impact of the outlier.
