Particular Cases of the Calculation of the Errors (Uncertainties) of the Results of Direct Measurements with Multiple Observations

It is shown that an expression for the total error as defined in GOST 8.207-76 of the corrected results of a measurement possesses an anomaly when this error is less than one of its components, and that a similar anomaly occurs for the expanded uncertainty as defined in MI 2552-99. The error of uncorrected results of a measurement whose random component is distributed according to different laws is compared with calculations utilizing RD 50-453-84 and MI 1788-87.
