It confirms whether the primary hypothesis results derived were correct. Hypothesis testing is a formal procedure for investigating our ideas about the world using statistics.It is most often used by scientists to test specific predictions, called hypotheses, that arise from theories. Its importance stems from the fact that, in large samples, many testing problems . There are so many solved decision tree examples (real-life problems with solutions) that can be given to help you understand how decision tree diagram works. In this, the design of observational studies in econometrics is similar to the design of studies in other observational disciplines, such as astronomy, epidemiology, sociology and political science.
