Hi my dear friend,
Sampling is important because it is impossible to (observe, interview, survey, etc.) an entire population. ... In the context of research, sampling is the method one uses to gather and select, to sample, data. A data sample is a set of data collected from a statistical population by a defined procedure.
~Thank you
Answer:
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 it may include simple random sampling or systematic sampling.
Sampling saves money by allowing researchers to gather the same answers from a sample that they would receive from the population. Non-random sampling is significantly cheaper than random sampling, because it lowers the cost associated with finding people and collecting data from them.
