I. Methods of Statistics
The methods of statistics refer to the various approaches used by statistics to study and understand the quantitative aspects of objective phenomena. From the perspective of the research subject's activities, like many other scientific researches that require the processes of data collection, organization, and analysis, statistical research also undergoes these processes, which are known as statistical investigation, statistical organization, and statistical analysis in statistics.
