Megjegyzések:	The present issues contain the results of statistical price analyses in sugar sector. The analysis is based on processing data of five years, in which it tries to reflect the correlation of worldwide and national prices of the examined product chains, as well as the rate and tendency of the connection between production and consumption prices by the help pf different statistical methods. Investigations have mainly been based on conventional statistical methods, such as decompositional time?series models or two and multiple variable model analyses. Trend, correlation and regression analyses are based upon monthly figures from between 1998 and 2002. Analyses have been prepared by MS Excel Analysis Tool Pak, according to the following methods: After a diagrammatic presentments have defined the major statistic characteristics (i.e. standard deviation, error, etc) of collected time series data through descriptive statistic methods, which, in order to maintain comparability, was followed by a calculation of the coefficient of variation. Differences between minimum and maximum values were then expressed in percentage forms. Tentative goodness of fit tests were then performed to trace the best-fitting trend factor (relevant R2 value, the type of function, and the exact equation are indicated). Analysis Tool Pak's tool for handling adjunctions, which has been designed to perform parameter estimation, was incorporated to demonstrate results derived from regression statistics, analysis of variance and parameter estimation. The investigations, during which I managed to identify the coefficient of correlation and determination together with the parameters of function were performed according to the methodology discussed in relevant literature.
