Discussion Review data set (see Excel spreadsheet) – New vs old – Valid and invalid AC = acceptable for intended purpose, calibration test AG = acceptable for intended purpose, industry donated test, not for calibration (wire mesh filters) C = calibration test LC = operationally invalid as determined by lab, not in stats, calibration test OC = operationally valid, does not meet statistical criteria, calibration test ? = new test from email sent to some people Review plots (following pages) If the data set is the right one, and if it is agreed that the cause is liner material, then the correction might be 28.4 mg for average trwl (see analysis in Word document)
