Purpose of This Assessment The purpose of the final assessment for this competency is to demonstrate successful use of statistical tools within the context of a real-world situation. Item Required for Submission The item required for submission is a 12- to 15-page paper with the four distinct sections detailed below for a given case study from the perspective of a professional consultant. Step ONE: Primary Data Analysis Competency Name: Quantitative Fluency, Level B Competency Statement: Apply the concepts of statistical reasoning, data analysis, modeling, and interpretation. Summative Assessment Submission Title: Case Study Analysis Competency Objectives: 1. Analyze and interpret a statistical problem and determine the optimal solution. 2. Calculate and interpret descriptive and inferential statistical data. 3. Create and explain graphs and charts that contain statistical data. 4. Analyze and interpret real world problems using basic probability theory. 5. Explain hypothesis testing and its use in statistical analyses. 6. Analyze and interpret correlation and regression in a real world context. 7. Apply knowledge of statistics to a real-world project. Program Learning Outcomes: N/A Institutional Learning Outcomes: N/A Quantitative Fluency, Level B Summative Assessment: Outline & Rubric For the first section of your paper, follow the steps described below. • Select a case study from the Appendix at the end of this document and identify the basic question you, as the researcher, want to address using this information. • State the type of study (observational, correlational, experimental, etc.) and describe the sampling or experimental method used. • Describe the sample and population of interest for this study. • Identify the independent and dependent variable(s). • Determine the level of measurement (nominal, ordinal, interval, or ratio) for all variables. • Note confounding, lurking, or missing variables that have not been included in the case study. Step TWO: Examination of Descriptive Statistics The next step is to examine the data that are provided in the case study. For this section of your paper, you need to present the following information: • Provide a discussion of summary statistics connected to the case study: mean, median, mode, standard deviation, variance, and range, referring the reader to the appendix for tables with this information. • Describe the sample data are normally distributed, using an appropriate graphical display. Be sure to include why this verification is important. • Identify outliers (present or not). If present, how will they affect your analysis? Step THREE: Examination of Inferential Statistics In the third section of your paper, conduct a hypothesis test or correlational study, describing your hypotheses, assumptions, and the tests used. • State the null and alternative hypotheses. • Select the significance level and determine if it is a one- or two-tailed test. • Select your test statistic and use the traditional or p-value method to analyze the values you have obtained. • Make a decision. Step FOUR: Conclusions and Recommendations Quantitative Fluency, Level B Summative Assessment: Outline & Rubric The fourth section of your paper will require you to use the results from your hypothesis test or correlational study to explain the meaning of the results within the case study’s setting. • Make an observation about your population of interest based on the results of your sample analyses • Identify additional information that might lead you to a different conclusion. • Note any variables that might be missing, and how they could influence your findings. • Describe the qualitative or quantitative data that you would like to have in a subsequent analysis. • Find at least two similar studies that include descriptive statistics and compare the findings from those studies with yours. Be sure to reference at least two scholarly sources and include them in your reference page. Step FIVE: Complete Checklist for Submission Before you submit, check to see if you believe you have met the criteria noted below.
