Attached are the documents needed for the second assignment. I attached the first assignment graded with the two changes recommended by the professor. The first assignment can be used to complete this assignment it just needs to reflect the changes. I have also attached the grading rubric.

STAT200: Assignment #2 - Descriptive Statistics Analysis and Writeup - Instructions Page 1 of 3 STAT200 Introduction to Statistics Assignment #2: Descriptive Statistics Analysis and Writeup Assignment #2: Descriptive Statistics Analysis and Writeup In the first assignment (Assignment #1: Descriptive Statistics Analysis Data Plan), you developed a scenario about annual household expenditures and a plan for analyzing the data using descriptive statistic methods. The purpose of this assignment is to carry out the descriptive statistics analysis plan and write up the results. The expected outcome of this assignment is a two to three page write-up of the findings from your analysis as well as a recommendation. Assignment Steps: Step #1: Review Feedback from Your Instructor Before performing any analysis, please make sure to review your instructor’s feedback on Assignment #1: Descriptive Statistics Data Analysis Plan. Based on the feedback, modify variables, tables, and selected statistics, graphs, and tables, if needed. Step #2: Perform Descriptive Statistic Analysis Task 1: Look at the dataset. • (Re)Familiarize yourself with the variables. Review Table 1: Variables Selected for the Analysis you generated for the first assignment as well as your instructor’s feedback. In addition, look at the data dictionary contained in the data set for information about the variables. • Select the variables you need for the analysis. Task 2: Complete your data analysis, as outlined in your first assignment, with any needed modifications, based on your instructor’s feedback. • Calculate Measures of Central Tendency and Variability. Use the information from Assignment #1 - Table 2. Numerical Summaries of the Selected Variables. Here again, be sure to see your instructor’s feedback and incorporate into the analysis. • Prepare Graphs and/or Tables. Use the information from Assignment #1 - Table 3. Type of Graphs and/or Tables for Selected Variables. Here again, be sure to see your instructor’s feedback and incorporate into the analysis. STAT200: Assignment #2 - Descriptive Statistics Analysis and Writeup - Instructions Page 2 of 3 Step #3: Write-up findings using the Provided Template For this part of the assignment, write a short 2-3 page write-up of the process you followed and the findings from your analysis. You will describe, in words, the statistical analysis used and present the results in both statistical/text and graphic formats. Here are the main sections for this assignment: ✓ Identifying Information. Fill in information on name, class, instructor, and date. ✓ Introduction. For this section, use the same scenario you submitted for the first assignment and modified using your instructor’s feedback, if needed. Include Table 1 (Table 1: Variables Selected for the Analysis) you used in Assignment #1 to show the variables you selected for the analysis. ✓ Data Set Description and Method Used for Analysis. Briefly describe the data set, using information provided in the data set file. Also describe what method(s) (i.e., TI Calculator, free web applets, Excel) you used to analyze the data. ✓ Results. In this section, you will report the results of your descriptive statistics data analysis. For each variable, fill in the following sections: • Variable (#): (Name). Fill in the name of the variable. Note: Income was included for variable 1. • Numerical Summary. Fill in Table . Descriptive Analysis for Variable with your computation. Below is the template table; be sure to include the name(s) of the measures used as well as their values. Since there will be no measure of dispersion for the qualitative variable, just enter N/A for not applicable. Note: The information for the required variable, “Income,” has already been partially completed and can be used as a guide for completing information on the remaining variables. Variable n Measure(s) of Central Tendency Measure(s) of Dispersion Variable: • Graph and/or Table. Put the graph or table for the variable in this section. STAT200: Assignment #2 - Descriptive Statistics Analysis and Writeup - Instructions Page 3 of 3 • Description of Findings. - Briefly describe the descriptive statistics measure(s) that was/were calculated and explain why was it/they the appropriate one(s) to use. - Describe the results of the analysis in everyday language. Please consult your textbook and information contained in our LEO classroom for examples. ✓ Discussion and Conclusion. Organize the discussion to address findings for which you presented results. Briefly discuss each variable in the same sequence as presented in the results. What has the highest expenditure? What variable has the lowest expenditure? If you were to recommend a place to save money, which expenditure would it be and why? Note: The section should be no more than 2 paragraphs. Assignment Submission: Name the file that contains your completed “Assignment #2: Descriptive Statistics Analysis Writeup Template” using the following format: “Assignment2-StudentLastName.” Submit it via the Assignments area in the LEO classroom in the “Assignment #2: Descriptive Statistics Analysis Writeup” folder.

I am a 36 year old married man with two children working in the US Army while completing a bachelor’s degree. My income is $60,000 per year. In addition to income, four variables include: SE-Marital status, SE-Family size, USD-Food, and USD-Meat. Use Table 1 to report the variables selected for this assignment. 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. Table 1. Variables Selected for the Analysis Variable Name in the Data Set Description (See the data dictionary for describing the variables.) Type of Variable (Qualitative or Quantitative) Variable 1: Income Annual household income in USD. Quantitative Variable 2: Marital Status Marital status of Head of Household Qualitative Variable 3: Family Size Total number of people in family. Quantitative Variable 4: Food Total amount of annual expenditures on food. Quantitative Variable 5: Age Household Age of the Head of Household (in years) Quantitative Reason(s) for Selecting the Variables and Expected Outcome(s): Variable 1: “Income” - Variable 1: “Income” - The income I chose is the average income that an E8/MSG makes in the Variable 2: “Marital Status“– Military Status alters the amount of compensation Soldiers receive to support their families. In addition, this variable can have an effect on how much comes to the households and how the money is use. More income doesn’t necessary equates to better budgeting. Variable 3: “Family Size“ - This variable shows the size of the family. Households’ income is greatly impacted with by the size of their families. Most military families have two to three kids. Variable 4: “Food“ - This variable will show how much is the annual food expenses for the family. This hoping most families categorizes all food supplies (i.e. meet, fruits) as food. Variable 5: “Age Household s“ - This variable will discuss the age of the primary providers. Data Set Description: Proposed Data Analysis: Measures of Central Tendency and Dispersion Complete Table 2. Numerical Summaries of the Selected Variables and 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. Table 2.
