Project  Use the Statistics Class dataset
For this Project, you will use the “Statistics Class” dataset called Stat_Grades.sav, which can be found in the Doc Sharing area under the Graded Projects category. This same “Statistics Class” dataset is used for all the class projects. There is a full description of this dataset in the Graded Projects category of the Doc Sharing area. The Stat_Grades.sav dataset contains data collected about students in three sections of a statistics class taught by an instructor. You will also use SPSS for this project.
HINTS AND HELP
Note: When asked to include the interpretation of the results and final conclusions, be sure to include all results, an interpretation of the meaning of the results, and final conclusions that a common person can understand. Make sure you use complete sentences, paragraph form (single spacing), proper grammar, and correct spelling. Minimal or incomplete responses can lose points. Include any SPSS results that you use, but do not include SPSS results that are not part of your solution.
Hint: You are asked to determine “appropriate” tests and methods, and to make calculations. This means that you will have to determine which tests or methods are best and why.
Rememberto always show all of your work and each of your steps.
For each question, follow the appropriate steps.
1) Write the hypothesis
2) Construct the Ho and Ha clearly and appropriately. Note the means you are comparing.
3) Run the appropriate SPSS test and include the appropriate results
4) Explain and evaluate the SPSS results
5) Write a complete and paragraph form conclusion that can be understood by a normal nonstatistical person.

Student work demonstrates mastery of the objectives assessed by the project. This is evidenced by at least the following: · The selection of the statistical procedure(s) is/are the most appropriate ones for answering the questions; specifically, the correct ttest is selected for each question. · The statistical procedure was calculated correctly using SPSS. · The interpretation of the SPSS output is correct and complete, including applying the Sig. (2tailed) pvalue to determine null hypothesis rejection. · The results of the statistical analyses are presented in easy to understand, nonstatistical language that addresses the research question. · SPSS output that is not needed in the solution is not included. Only appropriate SPSS output are included. · Each step of the hypothesis testing procedure is included, including the statement of the hypothesis, inclusion of the null and alternative hypothesis Ho and Ha, results from the hypothesis ttest, and complete clearly written conclusions. 
Research Project Instructions: Using the Statistics Class dataset called “Stat_Grades.sav”, answer the following. Use alpha = .05
1. The Instructor of the Stat_Grades.sav class decided to provide additional opportunities for the students in the class to learn the class materials. To accomplish this, the Instructor offered all students the option to attend a set of review sessions. The Instructor believes that offering these review sessions will help student performance. Using the appropriate tests, methods, and evaluations, determine if attending the Review sessions made a significant difference in students Total Course Points. Be sure to include each step of the process, any SPSS results used, an interpretation of the results, and final conclusions.
2. Based on many years of past classes and experience, the Instructor for the Stat_Grades.sav class has determined that a Percent for the Course of 85% describes a successful class. Does the Instructor’s current Stat_Grades.sav Percent for the Course differ significantly from what is considered to be normally successful? Use and include the appropriate tests, methods, and evaluations. Be sure to include each step of the process, any SPSS results used, an interpretation of the results, and final conclusions.
3. Using the Stat_Grades.sav dataset for students, compare Quiz 1 and Quiz 3 and determine if there is a statistically significant difference in the average student performance between these two quizzes. Use and include the appropriate tests, methods, and evaluations. Be sure to include each step of the process, any SPSS results used, an interpretation of the results, and final conclusions.
