STAT200 Introduction to Statistics Dataset for Written Assignmen ✓ Solved

STAT200 Introduction to Statistics Assignment #2: Descriptive Statistics Analysis and Writeup. 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.
• 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.
• Prepared Graphs and/or Tables: Use the information from Assignment #1 - Table 3. Type of Graphs and/or Tables for Selected Variables.

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.
• Introduction. For this section, use the same scenario you submitted for the first assignment and modified using your instructor’s feedback, if needed.
• Data Set Description and Method Used for Analysis.
• Results. In this section, you will report the results of your descriptive statistics data analysis for each variable.
• Description of Findings.
• Discussion and Conclusion. Organize the discussion to address findings for which you presented results.

Introduction:

The dataset analyzed in this assignment stems from the US Department of Labor’s 2016 Consumer Expenditure Surveys (CE), providing a comprehensive overview of household expenditures and socioeconomic details. This analysis aims to deliver insights into the financial characteristics of a sample of 30 households regarding their spending on food, entertainment, education, and overall expenses.

As established in the first assignment, I have selected the following variables for analysis:

Data Set Description and Method Used for Analysis:

This dataset contains crucial information regarding income levels, age, family size, and related expenditures which were used to evaluate household financial health. The analysis involved the following statistical methods: measures of central tendency (mean and median) and measures of dispersion (standard deviation). These methods were completed using statistical software and calculations as outlined in the Assignment #1 data plan.

Results:

Variable 1: Income

Numerical Summary:

Graph: A histogram of income distribution is presented below.

Variable 2: Age Head Household

Numerical Summary:

Graph: A box plot demonstrating the distribution of ages is displayed.

Variable 3: Family Size

Numerical Summary:

Graph: A pie chart indicating family size distribution is included.

Variable 4: Food Expenditures

Numerical Summary:

Graph: A histogram for food expenditures shows data distribution.

Variable 5: Entertainment Expenditures

Numerical Summary:

Graph: Displayed in a histogram is the entertainment expenditure data.

Description of Findings:

The analysis provided insightful perspectives on household expenditures and socioeconomic profiles. The average income suggests a stable economic condition, while the median income reflects that a portion of the sample earns significantly more. Family size appears consistent with average income levels, and food expenditures demonstrate responsive budgeting, wherein families align their food spending according to their overall socioeconomic status.

Discussion and Conclusion:

In conclusion, the analysis revealed that entertainment expenditure was the least among the variables analyzed, suggesting it may be an area for potential savings. In contrast, food expenditures remain a significant financial commitment, necessitating careful budgeting to leverage savings. Through this analysis, a clear understanding of household expenditure behavior has emerged, providing a foundation for future financial planning.
