Quantitative methods of sociological research are based on interrogating a certain number of respondents and allow for the obtaining of numeric values of the subject of research.
Quantitative research received its name due to its aim at obtaining quantitative information about a large number of objects of research. Such research is designed to study objective, quantifiable characteristics of human behaviour. It is used when precise, statistically reliable data are needed.
Quantitative methods of research are used most frequently, for they allow for extrapolating the results of research to the aggregate, and speaking about the population of a country or a region in general due to encompassing large numbers of respondents.
Methodologies of quantitative research are always based on strict statistical models, large samplings are used which allows one to find out the quantitative (numeric) values of the indexes that are being researched. Sampling in quantitative research must comply with rigid requirements based on probability theory and mathematical statistics. Data processing in such research is done with pattern procedures of quantitative nature. Research results are statistically reliable and can be extrapolated on the whole population of a region or on the group which the research was targeted at.
Quantitative methods are recommended:
· To determine the frequency and amount of commodity consumption
· To compare relative efficiencies of available concepts
· To determine information sources
· For public opinion research
Quantitative research methods:
