Complete a research report in which you form a hypothesis and then conduct a statistical analysis on the data in order to determine whether the hypothesis is accurate or not. Introduction Note: The assessments in this course build upon each other, so you are strongly encouraged to complete them in sequence. When we examine the relationships between variables where two or more variables are characterized by nominal or categorical groups, we may use a chi-square test of significance. The chi-square test examines the statistical significance of the differences between observed and expected frequency count in each cell of a table. The chi-square test tells you only whether a statistical significance of difference exists between groups on some other categorical variable (neither strength nor direction). Throughout the course, you been exploring various concepts and building your skills in statistical analysis. In this assessment, you will discuss the steps taken to build a research study, which includes a literature review, hypothesis, research methods, data analysis, and your results. Overview Note: The assessments in this course build upon each other, so you are strongly encouraged to complete them in sequence. This course exercises many skills related to understanding statistical procedures and analysis. For this assessment, you have the opportunity to incorporate many of the skills discussed in this course into a research report. You will use the data from the “grades.sav” SPSS file included in this course, form a hypothesis, and then conduct a statistical analysis on the data in order to determine whether the hypothesis is accurate or not. In addition, you will record the results and make conclusions based on the hypothesis you originally designed. Having the ability to connect all the concepts to apply research and real variables ensures you understand the various methods of statistical analysis. Preparation Download the SPSS data file grades.sav and save the file for future reference on your computer’s hard drive in a place where you will remember where it is. Review the associated variable structure table for the data set titled “cf_data_set_instructions.pdf” which includes the names and scales of measurement for each of the variables in the data set. Decide Your Variables Begin by selecting two variables of your choice from the following list of variables. List A—Independent Variables gender. ethnicity. year. lowup. section. extcr. List B—Dependent Variables gpa. quiz1. quiz2. quiz3. quiz4. quiz5. final. total. percent. grade. passfail. Extract Your Data After you’ve extracted your data, design a research topic involving the two selected variables. For example, if you select “quiz1” and “total,” you may want to research the peer-reviewed education literature on the relationship, if any, between quiz scores and total scores in a course. Consult the Resources for this assessment for guidance on searching for sources. You should have a total of six sources. For each source, write 1–2 paragraphs that includes a main idea, evidence from the source, and an analysis. Hypothesis. Include both null and alternate hypotheses. Methods. Participants. Describe the number of participants in the study. For this archival data project, the number of participants refers to the number of participants who responded to both of your selected variables. Measures. Discuss the measurement you chose from your work throughout the course. Data Analysis. Explain the form of analysis that you used to manipulate your data. Consider the following questions in your explanation. From the point that you had the raw data, what test did you run? Why did you select that test? Why did you choose to manipulate the data? How did you manipulate the data? What results did you desire? Results. Report the results of your statistical analysis. Reflect on whether your null hypothesis or alternate hypothesis is correct. Make a conclusion in regard to the relationship between the variables. Discussion. Discuss your results in relation to the following: How do your results compare to other research studies? How can your results be generalized? What were the limitations of the study? Is your research valid and reliable? Or, how would you evaluate the validity and reliability of your study? Submission Requirements Submit the completed 6–8 page template as your deliverable for assessment. Be sure that you have cited all sources in APA style. Competencies Measured By successfully completing this assessment, you will demonstrate your proficiency in the course competencies through the following assessment scoring guide criteria: Competency 1: Apply appropriate notation, terminology, procedures, and concepts to statistics problems. Explain the rationale for a selected measurement for a research study. Describe conditions of the research findings that can be appropriately generalized. Competency 3: Evaluate confidence and significance of statistical data. Describe participants in relation to selected variables in a research study. Explain the data analysis process for a research study. Explain the reliability and validity of conclusions. Competency 4: Apply quantitative analysis to individual, organizational, and social issues. Report the results of a statistical analysis. Discuss the conclusions of a research study. Competency 5: Communicate quantitative analysis effectively in a manner consistent with expectations for psychology professionals. Support hypothesis and arguments with relevant scholarly literature. Convey purpose, in an appropriate tone and style, incorporating supporting evidence and adhering to organizational, professional, and scholarly writing standards.
