# Torque/angle statistic category

In the upper part of the Run inspection page, tap Torque/Angle statistics to displayed the statistics parameters related to the measured torque/angle values.

The following parameters are shown:

- Samples: it is the number of acquired results.

- Minimum: it is the minimum value between the results of the Inspection.

- Maximum: it is the maximum value between the results of the Inspection.

- Range: it is the range value according to ISO norm.

- Average: it is the average value of the results of the Inspection.

- STD (σ): it is the standard deviation (indicated with the Greek letter “Sigma”) of the results of the Inspection.

- 3σ/X: it is the value of the “3 sigma percentage” parameter (3 times the standard deviation) over the average value according to ISO norm.

- X-3σ: it is the value of the “mean minus 3 times the standard deviation (sigma)” parameter according to ISO norm.

- X+3σ: it is the value of the “mean plus 3 times the standard deviation (sigma)” parameter according to ISO norm.

- Cm: it is the Cm value according to ISO norm.

- Cmk: it is the Cmk value according to ISO norm.

- CAM: it is the CAM value according to CNOMO norm.

- Cpk: it is the Cpk value according to CNOMO norm.

- CNOMO Mean range: it is the mean range value according to CNOMO norm.

- CNOMO Istantaneous STD (σ): it is the istantaneous deviation (indicated with the Greek letter “Sigma”) of the results of the Inspection according to CNOMO norm.

- CNOMO STD (σ): it is the standard deviation (indicated with the Greek letter “Sigma”) of the results of the Inspection according to CNOMO norm.

- OK: it is the percentage value of the results between minimum and maximum limit.

- Low: it is the percentage value of the results under the minimum limit.

- High: it is the percentage value of the results over the maximum limit.

After every new result, all the “Torque statistic” parameters are updated accordingly.
