1.Jackson (2012) even-numbered Chapter Exercises (p. 244). ·  2. You read in a health magazine about a study in which a new therapy technique for depression was examined. A group of depressed individuals volunteered to participate in the study, which lasted 9 months. There were 50 subjects at the beginning of the study and 29 at the end of the 9 months. The researchers claimed that of those who completed the program, 85%improved. What possible confounds can you identify in this study? ·  4. What are internal validity and external validity, and why are they so important to researchers? ·  6. What are the similarities and differences between within-subjects and matched-subjects 2.What is the purpose of conducting an experiment? How does an experimental design accomplish its purpose? 3.What are the advantages and disadvantages of an experimental design in a business study? 4.What is more important in an experimental study, designing the study in order to make strong internal validity claims or strong external validity claims? Why? 5.In an experiment, what is a control? What is the purpose of a control group? Of single or multiple comparison groups? 6.What are confounds? Give an example of a design that has three confounds. Describe three ways to alter the design to address these confounds and explain the advantages and disadvantages of each. 7.What does “cause” mean and why is it an important concept in research? How are correlation and causation related? 8.You are a researcher interested in addressing the question: does smiling cause mood to rise (i.e., become more positive)? Sketch between-participants, within-participants, and matched-participants designs that address this question and discuss the advantages and disadvantages of each to yielding data that help you answer the question. Describe and discuss each design in 4-5 sentences. Support your paper with a minimum of 5 resources. In addition to these specified resources, other appropriate scholarly resources, including older articles, may be included.

As a current or future health care administration leader, how will you decide which statistical test is most appropriate for the goal of monitoring, tracking, or overseeing operations in your health services organization?Each statistical test is dependent on a given set of research parameters and expectations. As you have examined throughout this course, understanding why and when to use each statistical test is necessary in conducting the tests for process control and comparison. Thus, chi-square tests are useful for table data, ANOVA for a single quantitative dependent variable and categorical independent variables, and ANOM for analysis of mean differences. Regression modeling is useful for determining the influence of independent variables on a quantitative dependent variable.For this Assignment, review the resources for this week regarding chi-square, ANOVA, ANOM, and regression. Pay particular attention to the examples shown in the textbook.(4–5 pages)Using SPSS and Microsoft Word, complete problems 1 through 10. Show all work. Submit both your SPSS and Word files.
