Statistics In Decision Making

Use the following data set to answer the following questions. To earn full credit show all of your calculations and other work. Explain your answers. Don’t just write a number.

The 26 students who signed up for General Psychology reported their GPA. Each person was matched with another person on the basis of the GPAs, and two groups were formed. One group was taught with the traditional lecture method by Professor Nouveau. The other class could access the Web for the same lectures whenever they wished. At the end of the term, both classes took the same comprehensive final exam, and they also filled out a “Satisfaction Questionnaire.” Scores on both measures are shown below.

Analyze the data with t tests and effect size indexes. Write a conclusion.

You can use the JASP Software to perform your analysis. Make sure you include the analysis output in your submission. Also, explain your results in detail.
