What does a rectangular distribution for Type B measurements assume?

• A. A specific measure of central tendency
• B. An equal probability between limits
• C. No probability distribution
• D. A biased measure

Answer: (B)

A rectangular distribution for Type B measurements assumes an equal probability between limits. This means that when estimating the uncertainty of a measurement, every possible value within a specified range is considered equally likely. The rectangular distribution indicates that there is no preference towards any particular value within the limits; all values are treated as equally probable. This uniform approach simplifies the analysis of uncertainty and provides a straightforward method for calculating the uncertainty associated with measurements that are believed to vary equally within a defined interval. The assumption of equality among possibilities is central to using this type of distribution effectively in various measurement contexts.
