Purposive sampling involves selecting participants for a study based on some characteristic that you know they have. There is nothing random about their selection - it was done with intent. An advantage of this type of sampling is that it allows the researcher to quickly hone in on the target population. A disadvantage to this form of sampling is that researcher bias can creep in to influence results, if subjects are not chosen very carefully.
random sampling
sampling theorem is used to know about sample signal.
in flat top sampling the electronic circuit required for sampling are less complicated as compared to the one used in natural sampling, at demodulation of the sample it is very difficult to maintain the natural waveform of the natural sampling so flat top sampling can easily be demodulated.
The sampling proportion may be used to scale up the results from a sample to that of the population. It is also used for designing stratified sampling.
Purposive sampling can allow the researcher to make generalizations about results. Purposive sampling also provides the researcher with many different sampling techniques.

The sample mean helps researchers maintain the scope of their research. If the sample mean is too far from the mean of the population then the numbers may be skewed.

Psychologists might select a sample for a survey using various methods, including random sampling, where every member of a population has an equal chance of being selected, or stratified sampling, which involves dividing the population into subgroups and sampling proportionally from each. They may also use convenience sampling, selecting individuals who are easily accessible, or purposive sampling, targeting specific groups relevant to the research question. The choice of method depends on the study's goals, the population of interest, and the resources available. Ensuring a representative sample is crucial for the validity of the survey results.
Institutions are purposive because we all know that without institution there will be no one to govern the behaviors of individuals, and there will be a possibility that our economy will be agitated.
