Excel formulas: VLOOKUP
, SUMIFS
, COUNTIFS
Pivot tables & charts
Descriptive statistics: mean, median, mode, variance
📊 Real-world Impact
Manager asks: “Why did profits drop in Q3?”

💡 Example
A colorful Power BI dashboard turns boring sales numbers into a story.
When your CEO says, “Wow, that’s clear!” — mission accomplished.

ETL (Extract, Transform, Load) pipelines
Cloud tools: Snowflake, Redshift, BigQuery
📊 Real-world Insight
Banks use ETL pipelines to move daily transaction data securely from apps to analytics servers.
Raw data is useless unless structured properly.
6️⃣ Machine learning (Optional but Game-Changing) 🤖
Add a predictive layer to your analysis.
💡 Example
Telecom analysts predict which customers will cancel subscriptions next month using logistic regression → saves millions in retention costs.
