| مستخلص: |
Measurement of geodetic parameters can be affected by a number of factors. These factors can have random or systematical character which can seriously devalue final results. One of the affecting factors is the inaccuracies of equipment which can directly influence measurement. Another negative impact are methods of measurement, environmental conditions and the state or experience of the surveyor. For a required determination for variable accuracy, it is necessary to make set of several observations from which we can define average value and precision. The paper describes analytical tools of small data sample used in geodesy with precision requirements. The work also brings to attention descriptive data analysis of data sample, assumptions about the independence, normality and homogeneity of sample. Finally, an evaluation of statistical significant value in dependence on named methods by hypothesis testing of dispersion and mean is presented. [ABSTRACT FROM AUTHOR] |
