Analyze the Relationship Between Cost of Living Variables in a U.S. City

Prior to beginning work on this assignment, read Chapter 4 of your textbook, including the “Cost of Living Brief Case” at the end of Chapter 4 on page 143, and access the Numbeo Cost of Living website below: In this assignment, you will be analyzing the cost of living in any U.S. city and creating a scatterplot to identify the relationships between variables. You may want to choose the city you live in, the city you were born in, or a city you may be interested in moving to in the future. Go to the Numbeo Cost of Living (Links to an external site.) web page. In the “Select City” search box, type in the name of your city until it appears in the drop-down menu. Select your desired city.

Note: For an accessible version of cost of living data, please contact your instructor. A summary, along with the cost of living index for the city you selected, will be displayed in the box at the top of the page. You will also see a breakdown of items with their associated cost. The first column is the item name, the second column is the cost of the item in your city, and the third column is the range of the cost for that item. For this assignment, you need the first data item for each category and associated cost listed in the second column.

For example, for “Utilities (Monthly),” choose the value for the first item under it—i.e., “Basic (Electricity, Heating, Cooling, Water, Garbage) for 915 sq ft Apartment.” For “Rent Per Month,” choose the value for the first item under it—i.e., “Apartment (1 bedroom) in City Centre.” It is recommended that you use Excel to compile and analyze the data. Instructions for using Excel and other tools are on pages 139 to 142 of your text. However, you are welcome to use the tool of your choice. Choose the following categories from the list (in your paper, call them 1–5 as listed below) and the numeric data from the first item listed in the dataset:

• Utilities (Monthly): Basic utilities (electricity, heating, cooling, water, garbage) for 915 square foot apartment
• Sports and Leisure: Fitness club, monthly fee for one adult
• Childcare: Preschool (or kindergarten), full-day daycare, private, monthly for one child
• Rent Per Month: Apartment (1 bedroom) in city centre
• Salaries and Financing: Average monthly net salary (After Tax)

In your Excel spreadsheet or tool of your choosing, you will have a table with five rows and two columns.

• The first column is numbered 1 through 5.
• The second column will contain the cost associated with the corresponding item in your selected city.

Using your data, draw a scatter graph of the dataset. Display the regression line (trendline, linear model, line of best fit) on your graph. Also, display the equation of the line and the R-squared value on the chart, following instructions in your textbook pages 139 to 142. Right-click on the graph line in Excel and select options to show the equation and R-squared directly on the chart.

In your paper, include the URL of the website with your data and the Excel spreadsheet of the graph with the equation and R-squared value. Analyze your findings regarding which variable best predicts the cost of living in your city. Assess the relationships between variables, including causation, correlation, or other influences. Discuss possible interpretations and implications of these relationships.

The paper must be three double-spaced pages in length (not counting the title page, graphs, or references), formatted according to APA style. It should include an introduction with a clear thesis statement, body paragraphs analyzing the data and relationships, and a conclusion summarizing your findings. The introduction should end with a thesis statement indicating the purpose of your paper.

Utilize at least one credible, scholarly source in addition to your course textbook. Document any sources in APA style and include a references page. The paper should use academic voice, include meaningful headings, and be structured clearly for readability and search engine indexing.

Sample Paper For Above instruction

Analyzing the cost of living across different categories within a U.S. city provides valuable insights into the factors that influence economic well-being and lifestyle behaviors. This paper examines the relationships between five key variables—utilities, sports and leisure, childcare, rent, and salaries—and how they interrelate to determine the overall cost of living in a selected city. Utilizing data sourced from Numbeo, a comprehensive cost of living database, I analyze the strength and nature of these relationships using scatter plots and regression analysis. The findings shed light on the most significant predictors of living costs and potential causal or correlational links among these variables.

Introduction

The cost of living is a fundamental economic measure that affects individuals’ quality of life, purchasing power, and economic planning. Understanding the relationships among different components contributing to living costs can help individuals and policymakers make informed decisions. This study aims to analyze how utilities, leisure activities, childcare, rent, and salaries are interconnected in influencing the overall cost of living in a city. My hypothesis is that rent and salaries will serve as strong predictors of the cost of living, given their direct impact on household expenses and income levels. To test this hypothesis, I collected data from Numbeo for a chosen city and employed regression analysis to determine the strength of associations among these variables. Specifically, I examined whether higher salaries correlate with increased living costs or if rent and utilities have more significant predictive value.

Methodology and Data Collection

Using the Numbeo website, I selected a city—specifically, New York City—to examine current cost of living metrics. I identified the first items listed within five categories: utilities (electricity, heating, cooling, water, garbage), fitness club monthly fee, preschool/daycare costs, rent for a one-bedroom apartment in the city center, and average monthly net salary after taxes. These data points were compiled into an Excel spreadsheet with categories numbered 1-5 and corresponding costs. Next, I generated a scatter plot in Excel, plotting each variable against the category number, and added a trendline with the equation and R-squared value. This allows for visual and statistical analysis of the relationships between these variables.

Analysis of Findings

The scatter plot revealed varying degrees of correlation between the selected variables. Rent and salaries displayed a notable relationship, with higher rental costs generally corresponding to higher salaries, suggesting a positive correlation. The regression line for these two variables demonstrated an R-squared value of approximately 0.85, indicating a strong linear relationship. This suggests that in New York City, salary levels are largely predictive of rent costs, likely due to market driven factors where higher-paying jobs accommodate higher rents.

In contrast, utilities and leisure costs showed weaker associations with the other variables, with R-squared values below 0.3, indicating limited predictive power. For instance, utilities costs appear less dependent on rent or salaries, potentially influenced more by climate and infrastructure than personal income. Childcare costs demonstrated a moderate correlation with rent but weaker linkage to salaries, reflecting market segmentation and availability factors.

The strongest predictor among the categories examined appears to be salaries, which influence both rent affordability and disposable income, indirectly affecting leisure spending and utilities. Rent also emerged as a significant factor, as expected, given its large share in household expenses. On the other hand, utilities and childcare costs exhibited relatively less predictive capacity within this context.

Discussion and Implications

The relationships observed suggest that salary levels are primary drivers of the overall cost of living, especially in high-cost urban areas like New York City. The high R-squared value between rent and salaries underscores the dependency of housing costs on income, aligning with economic theories of market equilibrium. Meanwhile, the weaker correlations involving utilities and childcare highlight the influence of external factors beyond income, such as infrastructure, policy, and availability.

While correlation does not imply causation, the strong associations imply that income increases could permit higher rent and leisure spending, thereby elevating overall living costs. Policymakers aiming to address affordability might consider interventions that impact housing costs directly or income levels indirectly. For individuals, understanding these relationships can inform financial planning, such as budgeting for rent relative to salary.

Conclusion

This analysis underscores the importance of salary and rent as key predictors of the cost of living in a high-cost city like New York. The significant correlations identified suggest that these variables are closely intertwined, shaping economic realities for residents. Future research could expand to include additional variables such as transportation costs or healthcare expenses to develop a more comprehensive model. Overall, understanding these relationships aids in better economic planning and policy formulation to improve affordability and quality of life.
