A contributor to an uncertainty estimate is designated as a triangular distribution. This value must be divided by the square root of 6 before being used. Why?

Question

Quizplus · Accepted Answer

Triangular distributions are often used to represent a range of uncertainty where the minimum and maximum values are known, but the most likely or expected value is not. In this case, dividing the range by the square root of 6 converts it to the equivalent of one standard deviation, which is a commonly used measure of uncertainty in statistics. This allows the triangular distribution to be compared and combined with other contributors to uncertainty that are expressed as standard deviations.
