Detailed explanation of the test process of parameter average value and variance in tensile testing machine

Instrument and instrument detection equipmentTension testerIt is widely used in tensile tests of various materials. The following is the statistical test process of Jinan Hengsi Shengda Instrument Co., Ltd. on how to obtain the average value and variance of the parameters in the tensile test machine.

First, the test statistics are calculated from the measured sample data. If the calculated statistical value falls into the rejection area at the agreed significance level a, it means that there is a statistically significant difference between the tested parameters at the agreed significance level a; otherwise, if the calculated statistical value falls into the acceptance field at the agreed significance level a, it means that there is no statistically significant difference between the tested parameters and is the parameter estimate of the same population. Parameter test is an important part of inferred statistics.

Tension testerTest data parameter inspection steps:

1. Propose null hypothesis and alternative hypothesis

2. Determine the appropriate inspection statistics

3. Specify significance level a

4. Calculate the value of the test statistics
