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.
An outlier is a data point that does not correspond with all the other data points. It will make the mean more accurate. If the outlier is higher, it will lower the mean. If the outlier is lower, it will raise the mean.
