Determination of Sample Size and Observation Units

The purpose of this study was to write programs to define sampling sizes and observation units by probability sampling methods and to provide an idea for software developers. The algorithms of the programs were written in Python 3. The programs may be run by double-clicking on the Windows operating system or by the command prompt of the DOS operating system. Each exe file has a memory space of 5 megabits on average. In this respect, the application files are very useful in terms of sharing by email and mobility by USB memory sticks.
