Assignment: The company you work for processes and uses crude oil in O

The company you work for processes and uses crude oil. In order to predict the price of production in the future, your manager wants you to analyze the historical price of crude oil. In looking at potential patterns, your company can use this information to help plan for the future. (Use the provided crude oil prices data below for the assignment)

Sample Paper For Above instruction

This paper presents a comprehensive analysis of the historical crude oil prices from January 2010 through September 2015. The objective is to identify trends and patterns that can inform future price predictions, aiding strategic planning for the company that processes and utilizes crude oil.

Data Collection and Preparation

Initial data compilation involved inputting the provided monthly crude oil prices into an Excel spreadsheet. The dataset included variables such as Month, Year, and Price (in dollars), forming the base for subsequent analyses. Data visualization and trend analysis require structured and accurate datasets, making this first step crucial for reliable insights.

Creating Visual Representations of Crude Oil Prices

The first visualization involved plotting the raw data in an XY chart on the "CrudeOilPriceData" worksheet. The chart's axes were labeled appropriately with the title "Crude Oil Price Trends (Jan 2010 - Sep 2015)". The X-axis represented the timeline (months and years), while the Y-axis depicted the price in dollars. Proper chart formatting included a clear legend, readable font sizes (10-12 pt), and professional aesthetics to facilitate interpretation.

Trend Analysis Techniques

To analyze trends, two separate worksheets were created: "PolyTrend" for polynomial trend lines, and "ExpTrend" for exponential trend lines. Each worksheet contained an XY chart based on the same dataset but employing different trend line models to examine the data's behavior over time.

Polynomial Trend Lines

On the "PolyTrend" worksheet, three polynomial trend lines of varying orders—quadratic (2nd order), cubic (3rd order), and 4th order polynomials—were fitted to the dataset. These trend lines help reveal nonlinear patterns that linear models might miss. Each trend line was formatted with distinct line styles and colors for clarity, and the chart included a descriptive title, axis labels, and a legend for reference.

Exponential Trend Line

On the "ExpTrend" worksheet, an exponential trend line was added to model the data's growth or decay pattern, which is common in commodity prices such as crude oil. This exponential trend line was displayed with an equation and R-squared value, indicating the fit's strength. Proper formatting ensured the chart was professional and interpretable.

Data Presentation and Formatting

All charts were formatted for clarity: font sizes were uniformly set to 10 or 12 points, with titles and labels appropriately sized for readability. Margins were adjusted to 0.5 inches on the left and right, and 1 inch on the top and bottom, complying with standard formatting guidelines. The upper left corner contained the student's name block, including the student's name, class title, and due date, with the general assignment title "Homework 2" positioned below.

Conclusion

The analysis of the crude oil prices over this period revealed significant fluctuations with discernible upward and downward trends. Polynomial trends of different orders provided varying degrees of fit, with higher-order polynomials capturing complex patterns. The exponential trend line effectively modeled the overall growth trend observed during the period. Understanding these patterns aids the company in forecasting future prices, allowing for strategic adjustments in production and resource planning.
