research design and t tests how are they connected 3

• This is a two part assignment
• Review the Learning Resources and the media programs related to t tests.
• Using the SPSS software, open the High School Longitudinal Study dataset found in this week’s Learning Resources and construct a research question that involves a comparison of a means test.

Part 1:Research Design and t Tests: How Are They Connected?

Use SPSS to answer the research question you constructed and post your response to the following:

1. What is your research question?
2. What is the null hypothesis for your question?
3. What research design would align with this question?
4. What comparison of means test was used to answer the question (be sure to defend the use of the test using the article you found in your search)?
5. What dependent variable was used and how is it measured?
6. What independent variable is used and how is it measured?
7. If you found significance, what is the strength of the effect?
8. Identify your research question and explain your results for a lay audience, what is the answer to your research question?

Be sure to support your Main Post and Response Post with reference to the week’s Learning Resources and other scholarly evidence in APA Style.

Part 2:Testing Hypotheses for Means

To prepare for this Assignment:

• Review the Learning Resources and the media programs related to t tests.
• For additional support, review the Skill Builder: Research Design and Statistical Design and the Skill Builder: Hypothesis Testing for Independent Samples t-test, which you can find by navigating back to your Blackboard Course Home Page. From there, locate the Skill Builder link in the left navigation pane.
• Also, review the t test scenarios found in this week’s Learning Resources and consider the three different approaches of t tests:
  • Independent sample t test
  • Paired sample t test
  • One sample t test
• Based on each of the three research scenarios provided, open the High School Longitudinal Study dataset or the Afrobarometer dataset from this week’s Learning Resources using SPSS software, then choose and run the appropriate t test.
• Once you perform your t test analyses, review Chapter 11 of the Wagner text to understand how to copy and paste your output into your Word document.

For this Assignment:

Write a 2- to 3-paragraph analysis of your t test results for each research scenario and include the SPSS syntax and output. Based on your results, provide an explanation of what the implications of social change might be.

Use proper APA format, citations, and referencing for your analysis, research questions, and output.
