Chauvenet’s Criterion

In the pressure gauge testing lab experiment, one of the requirements is that the “outliers” in the data are determined and excised from the analysis. One way of doing that is to apply Chauvenet’s Criterion. Below is a video of how that’s done and who Chauvenet was.

Note: he butchers the pronunciation of Chauvenet, sorry.

Fluid Mechanics Laboratory Video: Pressure Gauge Testing

Most of the theory is pretty basic and given in the video lecture.  The object of the test is to plot the deadweight pressures (reference) against those reported by the gauges.  The theory behind that is given in the monograph Least Squares Analysis and Curve Fitting.
