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.
In this example, -86 is an outlier. An outlier is any value that is numerically distant from most of the other data points in a set of data. We know that -86 is far below any of the other values in our data set. It is not uncommon to find an outlier in a data set.
