What is 'Sampling'. Sampling is a process used in statistical analysis in which a predetermined number of observations are taken from a larger population. The methodology used to sample from a larger population depends on the type of analysis being performed, but may include simple random sampling or systematic sampling.
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.
