Precise method for calculating quantity of repetitive trials // IOP Conf. Series: Materials Science and Engineering.

Abstract

The article analyzes a more precise method for calculating the quantity of repetitive trials required for an experimental research in the field of machine building. The work suggests, justifies and tabulates a new tn-criterion of the minimal required number of repetitive trials. It is established that the new method is versatile, gives more stable and precise results, does not require a large number of repetitive trials, can be used for any samples, for any measurement accuracy requirements and assume calculation confidence probabilities.
