# Assignment: Testing Hypotheses for Means

This week you have explored three different approaches to t tests. By this point, you know that each test has assumptions about the data and type of research questions it can answer. For this Assignment, you will be provided with three scenarios. As you read the scenarios, be sure and think about aligning the appropriate t test with the question. Consider whether the data are independent samples and if two samples are being compared.

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. Do not forget to evaluate if the t test assumptions are met, justify the selection of type of t test, and report the effect size. 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.

T-test
Research design
The authors used a correlation research design to conduct the study. They investigated the effects
of empathy and emotional intelligence on the reactive and proactive aggression amongst the
delinquents and non-delinquent juveniles.
Why they used t-test
The authors used a t-test because they wanted to compare the relationship between
variables and how that relationship changes between two different groups (Riasat et al., 2017).
The t-test would enable them to examine the effects emotional intelligence and empathy on the
two groups’ behaviors.
T-test was most appropriate
I this using a t-test was the best choice because it helped the authors to find valid results
and achieve the purpose of the study. The authors investigated two groups, delinquent and nondelinquent juveniles. Therefore, it was appropriate to use a t-test because all the data belonged to
