Sažetak

On the 28 Symposium of the Milk Industry (1990) the Analytical section was established, and necessity appeared to extend or renew the state of knowing applied statistical methods and interpretation of experimental data in relation to quality control of milk and dairy products. 1. Determination of random errors relative to analytical data - First part of paper involves some practical examples for determination of random error, when results are expressed as continuous or discrete values. 2. Calculation of random errors of analytical data expressed as discrete values -Four examples from analytical usage are given. Accuracy is examined of analytical determination of pasteurized milk container's air-hight' ness and determination of confidence intervals computed following Poisson and binomial distribution. 3. Comparison of analytical data relative to constituents and product's quality - Third part deals with values of parameters and comparison is made of experimental data from several treatments, as well as results of discrete values. Optimal sample size is determined.
