Week 6 assignment 1
Assignment 1: 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.
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.
By Day 7

Week 6 assignment 2
Assignment 2: t Tests in Practice
The practice of quantitative research not only involves
statistical calculations and formulas but also involves the understanding of
statistical techniques related to real world applications. You might not become
a quantitative researcher nor use statistical methods in your profession, but
as a consumer, citizen, and scholar-practitioner, it will be important for you
to become a critical consumer of research, which will empower you to read,
interpret, and evaluate the strength of claims made in scholarly material and
daily news.
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?
Did the authors display the data?
Do the results stand alone? Why or why not?
