Statistical Modelling, Sampling Errors, Environmental Aspects


In the paper the theoretical aspects of controlling accuracy of ash and sulphur contents in coal are discussed. The sampling error is considered as the main error of the measurement. The probability distribution function, the variance and the variation coefficient of a selected portion of grain and a whole characteristic have been used as criteria of sampling accuracy. The exemplary tests and simulations are attached.
