o    Introduce the Learning Team members and the data set.

o    Briefly explain how the data was gathered and identify the study population.

Descriptive Statistics

o    Define descriptive statistics and list the various descriptive measures.

o    Explain how descriptive statistical analysis increases understanding of the data.

o    Include an original graph created with StatCrunch that uses at least one descriptive statistical measure to illustrate the data set.

Inferential Statistics

o    Use StatCrunch to check the calculation and show the steps in your presentation.

o    Explain how inferential statistical analysis increases understanding of the data.

Null Hypothesis Testing

o    Explain the purpose of null hypothesis testing and provide examples of null hypotheses that may be tested with the data set.

o    Explain the logic of hypothesis testing and the role of the null hypothesis.

Implications for Future Research

o    Differentiate between descriptive and inferential statistics and how they support the human services research process.

o    Provide an example of a study that is a logical follow-up to your data set that yields useful descriptive data.

o    Provide an example of a study that is a logical follow-up to your data set that yields useful inferential statistics.

# BSHS 382 Week 3 Learning Team Research Proposal

http://www.assignmentcloud.com/BSHS-382/BSHS-382-Week-3-Learning-Team-Research-Proposal

The Research Proposal must be a 1,050- to 1,400-word proposal formatted according to APA 6th ed. guidelines. The Learning Team must identify a problem worthy of research and develop an outline of the process required to research it. No actual experiments must be conducted.

o    Provide your argument for the study and at least one example of past research that supports your argument.

o    Describe your variables and what they mean. For example, if I am measuring success, I define success as a student’s grade on their GRE exam. The success variable equals above average score on the GRE. Please use your own example.

Refer to Appendix A of Beginning Behavioral Research for an overview and examples of a research report.

Ethical Considerations

Write a 175- to 350-word summary identifying ethical considerations you must have in designing your research project.
