*University of Phoenix Material*
*Identifying Statistical Tests in the Literature Worksheet*
*Research* in the University Library to find three empirical (those containing data) research articles using one of the analytic methods studied this week (i.e., *z* test, independent sample *t* test, repeated measures *t* test).
*Select* articles that are of interest to you and include the citations at the end of this document.
Fill out the following tables and* answer *each question in 1 to 2 sentences.
Title of Article: *”The impact of geocoding method on the positional accuracy of residential burglaries reported to police” *It can be found in the university library. The article discusses the use of both z-test and t-test. But for purposes of this assignment we can discuss just the z-test aspect.
Question
Answer
What is the null hypothesis (implied or explicitly stated)?
What is the research hypothesis (implied or explicitly stated)?
What was the type of analysis (*z* test, independent sample *t* test, repeated measures *t* test) chosen, and why was it appropriate?
Z test was used in this article. This was appropriate so as to help in finding whether the two population means from the two samples were different more so since the sample size was large (Mazeika, D. <www.emerald.com/insight/search?q=David%20Mazeika> & Summerton, D. <www.emerald.com/insight/search?q=David%20Summerton>, 2017).
Title of Article: “*Quality of Life, Perceptions of Health and IIIness, and Complementary Therapy Use Among People with Type 2 Diabetes and Cardiovascular Disease.” *This can also be found in the UOP library. This article discusses the use of t-tests.

What was the type of analysis (*z* test, independent sample *t* test, repeated measures *t* test) chosen, and why was it appropriate?
Independent simple t test was used in this article. This was appropriate since the analysis involved two detached populations, CAM-user and non-user populations (Canaway, R. & Manderson, L., 2013)
