Definition of quantitative research
Quantitative research is an approach that seeks to determine the relationship between variables and cause and effect relationships. Normally， when researchers choose research questions they intend to investigate further， they identify hypotheses through literature review of other researchers’former studies. Literature review will help researchers to see if their research problems have already been done， and if there is still a gap. Thus their research hypotheses are usually built on past research to fill the gap. It is the research hypothesis that directs the researcher to the problem that needs to be solved.
Features of quantitative research
The purpose of quantitative research is to study relationships and cause and effect. The reasoning of quantitative research is deductive or top-down. The researcher uses standardized measurement and other quantitative instruments to measure what is observed. Data collected in quantitative are numbers and statistics. After collecting the data， the researcher uses statistical criteria or statistical means to analyze the data. Both the standardized instruments and statistical criteria can enhance the objectivity of the researcher. Quantitative researchers attempt to avoid the human bias and operate under the assumption of objectivity. Kervin， Vialle， Herrington，
