# testing hypothesis for a mean and critically evaluate a scholarly article related to t tests

THIS IS A 2 PART ASSIGNMENT. ALL THREE SCENARIOS HAVE TO BE DONE.

To prepare for this Assignment: Assignment 1: Testing Hypothesis for a Mean.

• 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.

ASSIGNMENT 2

For this Assignment, you will critically evaluate a scholarly article related to t tests.

To prepare for this Assignment:

• Search for and select a quantitative article specific to your discipline and related to t tests. Help with this task may be found in the Course guide and assignment help linked in this week’s Learning Resources.

For this Assignment:

Write a 2- to 3-page critique of the article. In your critique, include responses to the following:

• Why did the authors use this t test?
• Do you think it’s the most appropriate choice? Why or why not?
