The Chauvenet Criterion is used to eliminate the doubtful experimental findings obtained as a result of the measurement. As can be seen in the table below, the ratios of maximum acceptable deviations to standard deviations are given for various measurement numbers in this criterion.

In order to use the Chauvenet criterion, first of all, the σ standard deviation of the experiment and the di deviations of all cases must be known. Thereafter, each experimental finding should be compared with the criterion value in the table above. If some of the ratios for the experimental finding are greater than this critical value, these findings should be excluded.If desired, this criterion can be applied again for the second and third time to the new results obtained in this way. However, in practice, it is sufficient to apply this criterion once.

$\eta =\frac{x–x_m}{\sigma }$

E.g;
We have 10 values ​​and these values ​​are;

45.7
46.2
46.9
54.8
46.1
45.2
45.4
47.0
45.9
46.3

The mean of these values: 46.95
and the standard deviation of these values ​​is 2.673

Each value will then be subtracted from the mean and then divided by the standard deviation.

After this calculation, if these values ​​exceed the limit value in the table, this value will be subtracted from the measurement.

For example, for 54.8, the result of the above calculation is 2.94. 2.94>1.96 => negligible (The value of 1.96 is the maximum value for the result made for 10 values ​​from the table)

As a result of these, the analysis is to make the analysis with values ​​close to each other.
