A group of researchers conducted a study to investigate the effectiveness of a new teaching method for a particular subject. They randomly assigned 100 students to two groups: one group received the new teaching method, and the other group received the traditional teaching method. At the end of the semester, they measured the students' performance on a standardized test. The researchers found that the mean score for the group that received the new teaching method was higher than the mean score for the group that received the traditional teaching method. How can the researchers test the hypothesis that the new teaching method is more effective than the traditional teaching method? What statistical test should they use?

System Model Approaches

The systems model approach is a process-oriented representation that emphasizes the impact or flow of information between modules. The multidisciplinary study of the use of models to design and create systems in business and IT development is known as systems model approach. It models how processes interact and what these processes do, but it does not go into detail about how these processes are implemented. Functional decomposition may be utilized to enhance the models employed in this technique, and they can be coupled to requirements models for additional system partitioning.
