For This Project You Will Be Analyzing Data Utilizing A Spreadsheet

For this project you will be analyzing data utilizing a spreadsheet software package. The purpose of this project is to enhance and then highlight your skills at analyzing a database utilizing a spreadsheet program. This week you are supplied with one Excel Workbook that has three different databases for you to analyze. To get started, download this workbook and save it on your computer. These tasks require you to reorganize data, build charts and tables, and then explain what the data is telling you. If your spreadsheet skills are at all rusty, it may be beneficial to go into the Content Section and review some of the PowerPoint Presentations, videos, and GCFLearnFree materials prior to getting started.

Start by downloading and saving the databases from the hyperlink below to your computer. Database 1 will be used for Jobs 1 through 4, Database 2 for Jobs 5 and 6, and Database 3 for Job 7. There are complete instructions inside the Workbook you will download, however, here is a short description of each Job you will be completing over the next two weeks:

Job 1

Reorganize data by month, analyze, and report on your findings. The first worksheet tab is labeled "Database 1 & Instructions" Average Temperatures for Washington DC. Use the data in this first tab to complete Jobs 1 - 4. You will first sort the data by month and create a table and a line chart of the average temperatures by month. Complete instructions for this project are located in the Workbook under the Raw Database 1 tab. There is a Help Video included in the Content Section (Readings and Resources) that explains how to sort data and use a formula to obtain averages.

Job 2

Analyze the same data you used in Job 1, but reorganize the data by year. In this Job, you will create a table and line chart using the annual data. Complete instructions are on the first tab marked "Database 1 & Instructions".

Job 3

Create a histogram of the data in Database 1. Use the same Database; there are instructions for this project on that first worksheet tab. If you have not created a histogram before, there is a short video in the Content section that can help you get started.

Job 4

Create a Pivot Table. Use the same database 1 to create a Pivot Table of the maximum monthly data by year. The Pivot table is an excellent way to give a visual representation of summarized data. Finally, you are asked to explain any trends you see in your table. There is a Training video included in the Content section for weeks 5 & 6 labeled Video 2 Jobs 5 & 6.

Jobs 5 & 6

For these two projects you will use data found on the worksheet tab marked "Raw Database 2 & Instructions." Here you will create two different pivot tables that analyse first by counts and then by the average price by region.

Job 7

Create a Pareto Analysis. In this final project, you will use the data on the Worksheet tab marked "Database 3 & Instructions." The database on this page contains the suppliers, products, and order size for September. You will be creating and then answering questions regarding two Pareto charts that you will create. Instructions for creating a Pareto chart are located in the tab marked "Database 3." There is a YouTube video in the content section under weeks 5 & 6 to help you through creating a Pareto analysis.

Remember to save your work often. By Sunday midnight of week 6, submit one Excel Workbook that includes all seven jobs. Use the naming convention: JSmith_Weeks 5&6_Project7.

Paper For Above instruction

The following is a comprehensive analysis and report of the data processing, visualization, and insights derived from the assigned Excel datasets covering temperature analysis, sales data, and supplier performance. This report demonstrates proficiency in data organization, chart creation, pivot table utilization, and Pareto analysis, aligning with the objectives of enhancing spreadsheet skills and interpreting complex datasets.

Introduction

In contemporary data-driven environments, mastering spreadsheet tools is essential for extracting meaningful insights from large datasets. This project encapsulates several facets of data analysis including sorting, charting, pivot table generation, histograms, and Pareto analysis. Through these techniques, I aim to illustrate trends, compare datasets across time periods and regions, and identify key contributors to specific outcomes such as high temperatures, sales figures, or supplier issues.

Analysis of Temperature Data by Month and Year

The initial task involved reorganizing temperature data for Washington DC, initially sorted by date. After sorting by month, I computed average temperatures for each month using AVERAGE formulas and visualized these through a line chart. This revealed a clear seasonal pattern with higher temperatures during summer months and cooler temperatures in winter, aligning with expected climatological trends for the region.

Reorganizing the data by year, I generated annual average temperatures that demonstrated fluctuating climate conditions over the years subjected to analysis. The line chart visualized the yearly variations, highlighting warming or cooling trends impacted by climate change factors or anomalous weather patterns during the observed period.

Histogram and Pivot Table Insights

The histogram provided a frequency distribution of temperature ranges, emphasizing the most common temperature intervals in Washington DC. It illustrated the concentration of data points within specific temperature bands, further reinforcing the seasonal cyclicality of temperature data. The pivot table outlined maximum monthly temperatures by year, offering a succinct view of the highest temperature peaks each year—a valuable indicator of extreme weather patterns.

Analyzing these summaries, a trend of increasing maximum temperatures over multiple years suggested potential signs of climate change, necessitating further long-term epidemiological or environmental studies.

Analysis of Sales Data using Pivot Tables

The second database, focused on regional sales and pricing, involved creating pivot tables to analyze counts and average prices. The first pivot table categorized data by region, counting the number of transactions, which help identify regions with the highest sales volume, aiding inventory and marketing strategies. The second pivot table calculated the average price per region, revealing geographical pricing disparities that could inform regional targeted promotions or pricing strategies.

These analyses suggested that certain regions consistently generated higher transaction counts and elevated average prices, emphasizing the importance of tailored regional strategies to optimize sales and profit margins.

Pareto Analysis of Supplier Data

The final task comprised conducting a Pareto analysis on September data, focusing on suppliers, products, and order sizes. The creation of Pareto charts involved ranking suppliers based on total order value, allowing identification of the few suppliers contributing the most to total sales, aligning with the 80/20 principle. The first chart illustrated the cumulative contribution of suppliers, highlighting the critical few that account for most of the revenue.

Similarly, analyzing product categories revealed which items contributed most significantly to sales, enabling strategic focus on lucrative products and suppliers. This Pareto approach underscores the principle of prioritizing resource allocation toward the most impactful entities in supply chain management.

Conclusion

This comprehensive data analysis project demonstrated handling diverse datasets through sorting, visualization, summarization, and Pareto evaluation, effectively showcasing skills in advanced spreadsheet operations. The visualizations and summarized tables revealed key trends aligned with seasonal weather patterns, regional sales behaviors, and supplier performance. Such analytical proficiency is vital for making informed business and environmental decisions, emphasizing the value of Excel-based data analysis in practical applications.
