Pihnastyi // ARC Journal of Clinical Case Reports. – 2019. – Vol. 5, iss. 1. – P. 13-19.https://repository.kpi.kharkov.ua/handle/KhPI-Press/39722In this article, non-repeatable and repeatable sampling methods were analyzed. Main objectives connected with the use of sampling research method were determined. The problem of non-repeatable sampling amount defining at a given rate of bronchial asthma prevalence was analyzed. Key preconditions and assumptions used when constructing the expression to determine the non-repeatable and repeatable sample amount were depicted.ennon-repeatable sample amountrepeatable sample amountbronchial asthmaISAACresearch methodsstatistical population featureArticledx.doi.org/10.20431/2455-9806.0501004https://orcid.org/0000-0002-5424-9843
