Meaning and Comparison Analysis of the Terms Mean Square Error and Standard Deviation

Uz kraći prikaz povijesnog razvitka mjera za ocjenu kvalitete mjerenja i rezultata, dan je poseban osvrt i usporedbena analiza pojmova standardno odstupanje i srednja pogreška u skladu s međunarodnim dogovorom za iskazivanje mjerne nesigurnosti kojim je standardno odstupanje prihvaćeno kao osnovna mjera nesigurnosti rezultata.The paper presents the brief historical review of developing the measures for assessing the quality of measurements and results with special reference to comparison analysis of the terms "standard deviation" and "mean square error" according to the international agreement for expressing the uncertainty in measurement where the standard deviation has been adopted as the basic measure of the uncertainty of results
