Abstract

The possibility of using the methods developed in modern applied statistics for determining the lower confidence limit for the mathematical expectation of lognormal experimental values of a mechanical characteristic of soil, i.e. its 'calculated value', is studied. Practical considerations are given regarding the relative benefit of using the lognormal distribution in data processing as opposed to the normal distribution generally assumed for test results, especially with a small number of tests and real coefficients of variation.
