What is a DLL file? DLL files, also called Dynamic Link Libraries, contain a collection of executable functions and information that can be used by a variety of Windows programs. A .DLL file cannot run on its own. It is loaded and used by a program executable (EXE file), so you should not try to run them on their own.
Ideally, this is a population at risk. The study population is the population from which sample is to be drawn. Commonly, the population is found to be very large and in any research study, studying all population is often impractical or impossible. Therefore, sample unit gives researchers a manageable and representative subset of population.
A representative sample is a group or set chosen from a larger statistical population or group of factors or instances that adequately replicates the larger group according to whatever characteristic or quality is under study.his alone, however, is not enough to make the sampling bias negligible. Combining the random sampling technique with the representative sampling method leads to further reduced bias because no specific member of the representative population has a greater chance of selection into the sample than any other.
