Inferential statistics is a tool for studying a given population. Inferential statistics use measurements from the sample of subjects in the experiment to compare the treatment groups and make generalizations about the larger population of subjects.

Even if you dont follow a theoretical model youd surely be able to take a sample of one watch it and describe it. Inferential statistics can be contrasted with descriptive statistics. When analysing data such as the grades earned by 100 studentsit is possible to use both descriptive and inferential statisticsin your analysis.
It uses probability to reach conclusions.
Typically in most research conducted ongroups of people you will use both descriptive and inferential statistics toanalyse your results and draw conclusions. And what are their differences. The process of inferring insights from a sample data is called Inferential Statistics. Inferential statistics study the relationships between variables within a sample. Study results will vary from sample to sample strictly due to random chance ie sampling error. Inferential statistics use statistical models to help you compare your sample data to other samples or to previous research.
