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
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.
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 non-statistical person.
Use the Live Binder for further assistance. There is a link to the Live Binder under every Unit.
You may type and place your answers and SPSS results directly into this document.

Student work demonstrates mastery of the objectives assessed by the project. This is evidenced by at least the following:
selection of the statistical procedure(s) is/are the most appropriate
ones for answering the questions; specifically, the correct t-test is
selected for each question.
· The statistical procedure was calculated correctly using SPSS.
interpretation of the SPSS output is correct and complete, including
applying the Sig. (2-tailed) p-value to determine null hypothesis
results of the statistical analyses are presented in easy to
understand, non-statistical language that addresses the research
· SPSS output that is not needed in the solution is not included. Only appropriate SPSS output are included.
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 t-test, and complete
clearly written conclusions.
Research Project Instructions: Using the Statistics Class dataset called “Stat_Grades.sav”, answer the following. Use alpha = .05
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.
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
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.
