Dear colleagues, I have used the attached "Outlier Rejection
procedure" for over 20 years to detect outlier data from acquired
thermo-structural tests.
I have tried, unsuccessfully, offering the procedure to AEDC (Arnold
Engineering Development Center) because I use one of the two
Outlier Detection Methods but they have not shown interest.
Therefore, I am donating it to the PTC Community.
The method is a simple average of the of AEDC's and Chauvenet's
Outlier detection methods criteria resulting in the formula:
C_ABC(n) = (C(n)_AEDC + C(n)_Chauvenet(n)/2
Where "n = sample size"
Ultimately, entered the numerical results into TableCurve 2D
resulting in the formula provided in the attached workbook.
I have successfully used to determine the outlier of:
It is my hope that the community members will utilize the
ABC (AEDC-Banks-Chauvenet) Outlier Rejection Criterion.
to your particular applications.
Enjoy it ☺

Dear Werner_E, I have submitted the file before but I needed to replace it
with a file with corrected spelling of the name "Chauvenet". but I did not
find an option to replace the file. Therefore, I corrected the misspelled
name replacing the letter 'a' after the letter 'v' with the correct letter 'e'
as follows: Chauvenet.
Since I noticed that this file appears in Internet searches, I decided
to include the PDF-version of the Mathcad Prime v9.0 for the
convenient viewing by researches not having MC Prime.
One additional intention of including the PDF-version is that I personally
believe, without being asked by PTC, promoting Mathcad Prime over the
alternative software of MatLab and Mathematica. Ideally, I dream of the
day when engineering textbooks would use Mathcad as a substantial
competitive option.
Thanks,
