Which one of the following is not the way of estimating the statistical parameters and is integral part of analysis or synthesis tasks when probability of failure is involved? Correct Answer Propagation of weight

These are ways of estimating the statistical parameters describing weight or inertia and from which size and density are described. These methods are variously called

1. Propagation of error

2. Propagation of uncertainty

3. Propagation of dispersion

These methods are an integral part of analysis or synthesis tasks when the probability of failure is involved.

It is important that that good statical data and estimates are essential to perform and acceptable reliability analysis.
