In this assessment, you will use a data generator to produce data for your previously developed questions. You will then summarize the data by calculating various descriptive statistics and present the results graphically.
By successfully completing this assessment, you will demonstrate your proficiency in the following course competencies through the following assessment rubric criteria.
Competency 1: Interpret a data set’s central tendency and variability using descriptive statistical procedures.Calculate proportions correctly.
Calculate means correctly.
Calculate medians correctly.
Calculate modes correctly.
Calculate standard deviations correctly.
Calculate ranges correctly.
Competency 4: Solve problems in your personal and professional life by applying statistical procedures.Explain interesting findings or comparisons as a table, graph, or chart.
Complete your analysis (Parts 1–3) on one Excel sheet. Include the following components in your analysis of the data. You may wish to refer to the Analyzing Data With Descriptive Statistics Example [PDF] for further explanation. Note that to cover all the survey questions, your submission should include more tables, graphs, and charts than you see in the example.
PART 1: QUESTIONS 1, 2, 3, AND 4 (BINARY QUESTIONS)
Each question 1–4 should have the following elements:Sample size.
Sample proportion of each response.
Bar chart or pie chart.
PART 2: QUESTIONS 5 AND 6 (QUANTITATIVE QUESTIONS)
Questions 5 and 6 should have the following elements:Sample mean.
Sample median.
Sample mode.
Sample range.
Sample standard deviation.
Sample minimum and maximum.
Histogram.
PART 3: EXPLORATION OF DATA
Next, explore your data a bit further. What are two interesting findings from your survey responses? You might investigate responses for selected variables based on responses to your binomial questions. For example, if the answer to question 1 was Male or Female and to question 6 was Annual Income, you might examine the average annual income for males only and females only and compare these results. Present your findings in an appropriate table, graph, or chart. Then write, in the same Excel spreadsheet, a 1–2 paragraph summary of your findings.It is important to note that you should have:Four bar graphs (or four pie charts), one each for questions 1–4.
Two histograms, one each for questions 5 and 6.
Two tables, graphs, or charts to represent interesting findings from your survey responses. Include a 1–2 paragraph summary of your findings.
