Purposeful sampling is widely used in qualitative research for the identification and selection of information-rich cases related to the phenomenon of interest although there are several different purposeful sampling strategies, criterion sampling appears to be used most commonly in implementation. The cons of quantitative research here are the main disadvantages of quantitative research: • needs a huge sample of population: in using this type of research, you need to find great numbers of correspondents the larger the sample of people, the more statistically accurate the outputs will be. Sampling may be defined as the procedure in which a sample is selected from an individual or a group of people of certain kind for research purpose in sampling, the population is divided into a number of parts called sampling units. Systematic sampling is useful for many types of research, including any research types that require looking at individuals, such as human, plant or animal research systematic research basically means picking a percentage of the population to sample, then coming up with a concrete way of choosing that percentage, such as every 10th individual.

The research process outlined above is in fact an example of quota sampling, as the researcher did not take a random sample the advantages and disadvantages of quota sampling quota sampling comes with both advantages and disadvantages. Internet marketing research does not provide a random sampling of a target audience, which limits the utility of the results all an online marketing survey does is include answers from those who visit your site and decide to click on the survey.
