STAT200 Introduction to StatisticsPart 1: Descriptive Statistics Data Analysis PlanPart 1: Prepare Descriptive Statistics Data Analysis PlanBefore conducting any statistical analyses, researchers develop a plan for how they will analyze their data to answer their research questions. The purpose of this assignment is to provide an experience developing a descriptive statistics analysis plan. Note: This first part is a plan only; no statistics will be calculated or graphs created. The second part will involve carrying out the plan, after receiving feedback from your instructor.There are 3 steps (some with several “tasks”) that constitute Part 1:Step #1: Review the STAT200 data set file. (Note: This data set will be used for all three parts of this term project).The provided data set is a subsample of 31 data points from the US Department of Labor’s Consumer Expenditure Surveys (CE) and provides information about the composition of households and their annual expenditures (https://www.bls.gov/cex/). Detailed information on the sample and variables is included with the data set file; please carefully review this information to familiarize yourself with the data (Note: This information will be used in Part 2 to describe the dataset).Step #2: Develop descriptive statistics data analysis plan.Task 1: Develop a hypothetical “scenario”. Imagine that you are head of a household and have to determine a household budget plan based on the data available from the dataset. Please note that this “scenario” you describe is just to explain why you might be motivated to do this analysis. It does NOT have to be correct and/or true.As an example (note that this is an example; the data variables may not be the same as in our data set. You MUST create the scenario using the variables in our data set):”I am a 35 year old married parent (head of household) with one child. I earn $97,000 per year, and my annual total expenditures are $60,000; $20,000 of which goes to housing, $1,500 of it goes to the electric bill, and $600 is spent on water bills. I am curious to see how my income and expenditures relate to other people in the United States.”(NOTE: You do not need to put your actual income or any expenditure values in here–that is personal information that I do not need to know). A key point here is to ensure you use variables from the data set that accompany our section.Task 2: Select variables for analysis that match the scenario developed in Task 1. The data set provides information on household consumption; there are socioeconomic variables and expenditures variables. The socioeconomic variable names start with “SE-” and the expenditure variable names start with a “USD;” all expenditures are in US dollars.All students must use INCOME as one variable.
Select two additional socioeconomic variables (one qualitative: the only one is MARITAL STATUS) and one quantitative (either Age of Head of Household or Family Size)
Select two expenditure variables from ANNUAL EXPENDITURES, FOOD, HOUSING and TRANSPORTATION for your analysis that match the scenario you developed for Task 1.
For instance, using the example scenario of a 35 year old single parent with one child, you could select “income,” “marital status,” and “age of head of household” as socioeconomic variables and then pick two household expenditure items (such as “entertainment” and “education”) to show the distribution of costs and compare that with your income.When selecting variables, think about the following three questions:Why am I choosing these variables?
What interests me about these variables?
What do I think will be the outcome?
Answer the above questions in the section on the template labeled: “Reason(s) for Selecting the Variables and Expected Outcome(s):”.Task 3: Determine appropriate measures of central tendency and dispersion for the selected variables.For each quantitative variable, select at least one measure of central tendency and at least one measure of dispersion (see below table for list of measures). For the qualitative variable (Marital Status), select one measure of central tendency.When determining the measures of central tendency and dispersion, think about what is appropriate given the level of measurement and type of variable. Recommend referring to the text and information posted in our LEO classroom to help with this task (Note: you will use this information to provide a rationale for your choice of measures).Measures of Central Tendency:Mean
Mode
Median
Pie Chart
Bar Chart
Histogram
Box and Whisker Plot
Measures of Dispersion:Range
Sample Standard Deviation
Sample Variance
Frequency Table
Relative Frequency Table
Grouped Frequency Table
Task 4: Determine appropriate graph and/or table for each of the selected variables.Select one graph or table for each variable (Please see below table for list of graphs and tables). When determining the graphs and tables, think about what is appropriate given the level of measurement and type of variable. Recommend referring to the text and information posted in our LEO classroom to help with this task (Note: you will use this information to provide a rationale for your choice of graphs and/or tables).Types of Graphs:Types of Tables:Step #3: Complete the “Part 1: Descriptive Statistics Data Analysis Plan Template.” Remember, you will not be conducting any statistical analysis, drawing any graphs, or compiling any tables for the first assignment. Rather, you need to wait for feedback from your instructor on this part and use that feedback to complete Part 2 of the Term Project.In summary, here are the main components for this part:✓ Identifying Information. Fill in information on name, class, instructor, and date.✓ Scenario. In this section, briefly (2-3 sentences) describe the scenario you developed in Step #2, Task 1.✓ Complete Table 1: Variables Selected for the Analysis. Enter information the variables selected for analysis in Step #2, Task 2. For each selected variable be sure to include its: name as listed in the data set, description, and variable type.✓ Reason(s) for Selecting the Variables and Expected Outcome(s): In this section, for each selected variable, please answer the following questions:✓ Why did I choose this variable?✓ What interests me about this variable?✓ What do I think will be the outcome?✓ Complete Table 2. Numerical Summaries of the Selected Variables. Enter information on selected measures of central tendency and dispersion for each selected variable. Be sure to briefly explain why you choose those measurements.Note: The information for the required variable, “Income,” has already been completed and can be used as a guide for completing information on the remaining variables.✓ Complete Table 3. Type of Graphs and/or Tables for Selected Variables. Enter information on selected graph and/or table for each selected variable. Be sure to briefly explain why you choose those measurements.Note: The information for the required variable, “Income,” has already been completed and can be used as a guide for completing information on the remaining variables.
