Project #3561 - Statistics

In this assignment you will be using the data in the Stat_Grades.sav SPSS data set, which is the same one you used for the Unit 2 and Unit 4 projects. A description of the data set is provided in the Graded Projects section of Doc Sharing. You will need to have SPSS loaded to download this data file.

 

In this project you are given three research questions. You must develop the appropriate null and alternative hypothesis; select the appropriate statistical procedure to use to test those hypotheses; interpret the results from your analyses and provide an explanation of those results. Your explanation must be in the language of the research question. Be sure to include all of these in your submitted project.

 

Research Question 1:

The instructor provided additional opportunities for students to learn the material in the course by holding review sessions. Compare the two groups and determine if attending the review sessions made any significant difference in student's final points in the course? Based on your analysis, what would you tell the instructor?

 

 

Research Question 2:

Based on her experience the instructor determined that an acceptable mean value for final course percent for a successful class is 85%.  Does this class differ significantly from what she considers to be a successful class?

 

 

Research Question 3:

Compare Quiz 1 and Quiz 3 and determine if there is a statistically significant difference in the average student performance? Based on your comparison what is your conclusion?
