Hello, Data enthusiast, here is one of my practical projects as an internship with Quantum Analytics.
Visualization Tool: Excel/Pivot Table
Data Source: Quantum Analytics
The main objective of every Operational business is primarily focused on increasing revenue alongside customer satisfaction. However, in order to achieve this, different data are collected daily because these data are needed for stakeholders' decision-making. Businesses don’t just make decisions without proper data analysis.
Business Objective: To explore the Dataset and create an interactive dashboard to explain key Performance Indicators (KPI) such as Total Revenue and total Quantity and identify Yearly Accrued Revenue for the years involved, to identify the product or item that yielded the highest Revenue, Region that generated the highest Revenue.
Also, we want to know the salesperson who generated the highest Revenue in 2018 and 2019, the Top 10 Customers with the Highest Revenue, and the Customer with the Highest Quantity Purchase.
I will be doing Exploratory Data Analysis (EDA) for this dataset with the aim of increasing revenue. It involves the initial analysis of the data to discover patterns and insights which typically include:
Stage 1: Data Cleaning And Transformation
Identifying and handling missing values, outliers, and errors in the dataset. Understanding the data was my first project.
The Dataset has 17 Columns with about 2,000 rows. Few of the Columns are Order ID, Date, Customer ID, Customer Name, Sales Person, Region, etc
The “Order ID” Column was pre-formatted as text instead of numbers. So, I had to clean it using the “CLEAN” function in a different Column. I created a different Column for “Year” and “Month” using the “TEXT” function.
Moreso, because I needed to analyze sales by different quarters I created another Column for “Quarter” using a “TEXT” function nested with “OR” and “IF” functions. Thus:
Quarter = IF(OR(TEXT([@Date], “mmm”)=”Jan”, TEXT([@Date], “mmm”)=”Feb”, TEXT([@Date], “mmm”)=”Mar”), “Q1”,
IF(OR(TEXT([@Date], “mmm”)=”Apr”, TEXT([@Date], “mmm”)=”May”, TEXT([@Date], “mmm”)=”Jun”), “Q2”,
IF(OR(TEXT([@Date], “mmm”)=”Jul”, TEXT([@Date], “mmm”)=”Aug”, TEXT([@Date], “mmm”)=”Sep”), “Q3”,
IF(OR(TEXT([@Date], “mmm”)=”Oct”, TEXT([@Date], “mmm”)=”Nov”, TEXT([@Date], “mmm”)=”Dec”),”Q4"))))
May I use this opportunity to thank Mr. Jonathan Osagie, Quantum Analytics NG, and the entire facilitators.
Stage 2: Report, Visualization, and Dashboard
The ETL process has to be completed as far as a data Analyst is concerned. Once the cleaning and transformation process is completed, the next step is to load the data for analysis. I created a Pivot Table and Calculated the Sum of Revenue, the Sum of Quantity, and the Sum of Total Revenue.
I also created different tables such as Revenue by Sales Person, Revenue by item, Customer by Quantity Purchased, Revenue by Region, by Yearly Quarter, Revenue Over time, and Top 10 Customers by Revenue.
