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 an observation that appears to deviate markedly from other observations in the sample. Identification of potential outliers is important for the following reasons. An outlier may indicate bad data. For example, the data may have been coded incorrectly or an experiment may not have been run correctly.
