dc.description.abstract | In studies of population variability, particular attention has to be paid to the selection of a representative sample. The aim of this study was to assess the size of the new representative sample on the basis of the variability of chemical content of the initial sample on the example of a whitebark pine population. Statistical analysis included the content of 19 characteristics (terpene hydrocarbons and their derivates) of the initial sample of 10 elements (trees). It was determined that the new sample should contain 20 trees so that the mean value calculated from it represents a basic set with a probability higher than 95 %. Determination of the lower limit of the representative sample size that guarantees a satisfactory reliability of generalization proved to be very important in order to achieve cost efficiency of the research. | en |
dc.description.abstract | Cilj ovih istraživanja je da se na osnovu varijabilnosti hemijskih svojstava početnog uzorka proceni veličina novog reprezentativnog uzorka jedne populacije munike. Statističkom analizom je obuhvaćen sadržaj 19 svojstava (terpenskih ugljovodonika i njihovih derivata) početnog uzorka od 10 elemenata (stabala). Utvrđeno je da novi uzorak treba da sadrži 20 stabala da bi srednja vrednost izračunata iz njega reprezentovala osnovni skup sa verovatnoćom većom od 95 %. Određivanje donje granice veličine reprezentativnog uzorka koja garantuje zadovoljavajuću pouzdanost uopštavanja je veoma važno zbog ekonomičnosti istraživanja. | sr |
