When students first enter analytics, the subject can look bigger than it really is. The right way to learn it is one small idea at a time.
Case Background
Imagine a retail company that wants to understand revenue performance across products, cities, and months. A student analyst receives a transaction file and must identify the key patterns.
Approach
Start by cleaning missing dates and category labels. Then calculate total revenue, total orders, average order value, and monthly growth. Compare categories and regions using simple charts.
Possible Insight
You may find that one city generates the most revenue but another city has the highest average order value. This kind of contrast is exactly what makes case studies useful.
Portfolio Tip
When presenting the project, include the business question, data cleaning notes, KPI definitions, charts, and final recommendation.
