The best sampling is probability sampling, because it increases the likelihood of obtaining samples that are representative of the population.Simply random sampling This makes sure that every member of the population has an equal chance of selection.Defining the sample and collecting data are key parts of all empirical research, both qualitative and quantitative.For example, in our simple random sample of 25 employees, it would be possible to draw 25 men even if the population consisted of 125 women and 125 men.Back in September, I gave an example of an AOL poll that awarded all 50 states to John.Convenience sampling is used in exploratory research where the researcher is interested.The other reason why most researchers prefer random sampling over other research methods is the fact it represents the whole population.
The sample design may make use of the characteristics of the overall market population, but it does not have to be proportionally representative.

It may be necessary to draw a larger sample than would be expected from some parts of the population: for example, to select more from a minority grouping to ensure that sufficient data is obtained for analysis on such groups.
It would be expensive and time-consuming to collect data from the whole population of a market.Simple random sampling is the most basic and common type of sampling method used in quantitative social science research and in scientific research generally.In market research, sampling means getting opinions from a number of people, chosen from a specific group, in order to find out about the whole group.A simple random sample is a subset of a statistical population in which each member of the subset has an equal probability of being chosen.
