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 for a scatter plot is the point or points that are farthest from the regression line. There is at least one outlier on a scatter plot in most cases, and there is usually only one outlier. Note that outliers for a scatter plot are very different from outliers for a boxplot.
