On Determining the Volume of Repeated and Non-Repeated Sampling in the Preparation of Clinical Studies

In 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 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.
