How do you find the uncertainty of a sensor?

Experimental uncertainty is readily determined by repeating the experiment several times and computing the mean and standard deviation of the results. Statistical tests can then be used to determine if the results are significant.

What is uncertainty in data analysis?

Uncertainty is the quantitative estimation of error present in data; all measurements contain some uncertainty generated through systematic error and/or random error. Acknowledging the uncertainty of data is an important component of reporting the results of scientific investigation.

What is uncertainty in ISO 17025?

According to ISO/IEC 17025, testing laboratories must report uncertainty estimates where specified by the method, where required by the client and/or where the interpretation of the result could be compromised by a lack of knowledge of the uncertainty.
