Assignment: t Tests

As a social scientist, you will often construct research designs that require some sort of comparison between groups. When constructing hypothesis tests, the t test allows you to evaluate estimates from samples to determine if differences exist between these groups in the population. You might want to know whether a specific educational intervention has benefit, whether a training program works, or under what conditions employees are most effective. These are just a few examples where you might make comparisons between two groups. The t test's roots lie in solving practical questions about industrial quality control, which has led to it becoming one of the most fundamental and widely used tests in classical statistics.

In this week, you will examine t tests. In your examination, you will construct research questions, evaluate research design, and analyze results related to t tests. You also will critically evaluate research related to t tests.

Discussion: Research Design and t Tests: How Are They Connected?

Whether in a scholarly or practitioner setting, good research and data analysis should have the benefit of peer feedback. For this Discussion, you will post your response to the hypothesis test, along with the results. Be sure and remember that the goal is to obtain constructive feedback to improve the research and its interpretation, so please view this as an opportunity to learn from one another.

To prepare for this Discussion:

• Review the Learning Resources and the media programs related to t tests.

• 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. Also, you can use as a guide the Research Design Alignment Table located in this week's Learning Resources

Write a 3- to 5-paragraph critique of the article. In your critique, include responses to the following:

• Which is the research design used by the authors?

• 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?

• Did the authors report effect size? If yes, is this meaningful?

Be sure to support your Main Post and Response Post with reference to the week's Learning Resources and other scholarly Discussion: Research Design and t Tests: How Are They Connected?
