The paper is dedicated to the relationship of data aggregation level and variability of yields and prices of major crop plants. For that purpose yields and prices of the major crop plants in Poland are analysed i.e.: winter wheat, triticale, rye, barley, rape and sugar beet. The research are based on data from Polish FADN from years 2004-2009. The samples’ size ranged from S31 to 2893 for yields and from 183 to 1139 for prices, depending on the plant crop. In the paper six levels of data aggregation are examined, that is: farm, district, powiat, voivodship, region and country. It was found out that the degree of yield variability reduction (observed with data aggregation) is crop specific. por the price variability it is also true but to less extent. On general the reduction observed for the yield variability was much bigger than for the price variability. In the case of rape the reduction observed on the country level for yield variability was ten times higher than for the price variability.
