Question

Which distribution is related to U-probability distribution of Type-B evaluation of uncertainty?

(a) Arcsin distribution

(b) Binomial distribution

(c) Poisson distribution

(d) Bernoulli distribution

I have been asked this question during an internship interview.

I would like to ask this question from Type B Evaluation of Standard Uncertainty in section Evaluating Uncertainty in Measurement of Engineering Metrology

Answer 1

The correct option is (a) Arcsin distribution

The explanation: U-probability distribution of Type-B evaluation method of uncertainty is used when the values are at extreme limits and values are least at mean for example Arcsin distribution. Standard uncertainty = a/√2.
