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.
The interquartile range can be used to help detect outliers. All that we need to do is to is the following: 1  Calculate the interquartile range for our data. 2  Multiply the interquartile range (IQR) by the number 1.5. 3  Add 1.5 x (IQR) to the third quartile.
