Quantitative research methods include experiments, surveys and statistical analysis, among which the most typical method is questionnaire survey, which is a quantitative research method based on statistical principles. By using standardized questions, options and scales, the survey collected a large number of data samples, making the research results more objective and reliable. Researchers can analyze the collected data and use relevant statistical methods, such as frequency distribution analysis, correlation analysis, regression analysis and factor analysis. , discuss research issues and draw conclusions.
Experimental research is also one of the commonly used methods for quantitative research papers. The experimental study observes and measures the reactions and results of the subjects through the preset intervention operation, so as to explore the causal relationship between variables.
The experimental research can adopt single-factor experiment or multi-factor experiment, and can also adopt random experimental design to reduce errors and improve reliability.
In addition to the above methods, quantitative research papers can also use other statistical analysis methods, such as Bayesian statistics and multilevel models. These advanced statistical methods can analyze data more accurately, explore the complex relationship between variables, and improve the reliability and scientificity of research conclusions.
In a word, the main method of quantitative research papers is statistical analysis based on data. Through the collection, collation and analysis of a large number of digital data, the research problems are described and explained quantitatively, thus forming objective and scientific research conclusions and drawing scientific inferences.
