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.
Lesson Summary. An outlier is any value that is numerically distant from most of the other data points in a set of data. Measurement error, experiment error, and chance are common sources of outliers. The easiest way to detect an outlier is by creating a graph.
