Sampling in market research is of two types probability sampling and non-probability sampling. 2 Advantage: Flexibility. To understand more about purposive sampling, the different types of purposive sampling, and the advantages and disadvantages of this non-probability sampling technique, see the article: Purposive sampling. The simplest random sample allows all the units in the population to have an equal chance of being selected. A proper size of sample is maintained in order to have optimized results in terms of cost and efficiency. Scientific in nature. The standard error of the mean refers to the standard deviation of the distribution of sample means taken from a population. A sampling unit is a single member of the sample. The classic example of this advantage is that critical sample can be useful in determining the value of an investigation, while the expert sampling approach allows for an in-depth analysis of the information that is present. Since the methods used to collect data are based on scientific theory and results obtained can be tested, sampling is a more scientific method of collecting data. It is important to be aware of these, so you can decide if it is the best fit for your research design. different groups, some of which are related to the topic of the study, Ensures a high degree of representativeness of all the The sampling only chooses a part of the units from the population for the same study. The selection criteria the researcher uses can be very arbitrary and are almost always subjective. 7. The units of sample may be widely dispersed.
