This identification of the outliers will be achieved by finding the number of standard deviations that correspond to the bounds of the probability band around the mean (

Deletion of outlier data is a controversial practice frowned on by many scientists and science instructors; while
Chauvenet's criterion provides an objective and quantitative method for data rejection, it does not make the practice more scientifically or methodologically sound, especially in small
