Solve all!!!
A statistics teacher wanted to compare two methods of teaching introductory statistics. One method relied heavily on teaching the theory behind statistics (the theory method). The other method consisted of teaching the students various statistical tests and explaining when to use each test (the cookbook method). The teacher found that a leading engineering school was using the theory method in all its introductory statistics classes and that a local teacher's college was using the cookbook method in all its introductory statistics classes. At the end of each semester the teacher administered a standardized statistics test to both sets of classes.
What are the levels of the independent variable in this study?
What is a control variable used in this study?
What is type of experimental design is being used here?
The results indicated that the classes that received the theory method performed far better than did the classes that received the cookbook method. Can the teacher conclude that the theory method was the superior method and that is should be adopted by all statistics teachers? Explain why or why not.
How would you design a study to determine which teaching method for statistics is more effective so that it does not have a confounding variable?
