Question

Which type of uncertainty is evaluated in Type-B Evaluation?

(a) When observations are taken under same conditions

(b) When information has possible variability of input variables

(c) When Information is present non continuous manner

(d) When information is available and is used as it is without any judgement

I had been asked this question in class test.

Enquiry is from Type B Evaluation of Standard Uncertainty topic in portion Evaluating Uncertainty in Measurement of Engineering Metrology

Answer 1

Correct answer is (b) When information has possible variability of input variables

The explanation: The standard uncertainty where the available information is present with a possible variability of input variables is evaluated by Type-B method of evaluation. For making Type-B evaluations critical thinking, intellectual honesty and professional skill are required.
