Quantitative research is quantify data and generalize results from a sample to the people of the researching interest. Quantitative research is about asking people for their opinions. Usually a large number of cases representing the people of interest. Whatever I’m using a questionnaire or interview by selecting a sample of people or places for education research. I think that when use the quantitative research I can find out the data form myself. It’s important to survey sample people because I know that the most people of sample think. The data analysis of quantitative research has statistical data is usually in the form of tabulations. Findings are conclusive and usually descriptive. But the data analysis of qualitative research has non-statistical. So, I think that the data analysis of qualitative research might make the reliability of data reduced because there isn’t evidence and data that can be referenced.
