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.
The reason that an outlier differs from the rest of the points in the data set is crucial in determining whether to omit the outlier or not. Generally, outliers that can be attributed to an error of some sort-an error in measurement, recording, or experimental design, for instance-are omitted.
