• 📊 Pivot Tables: Summarize and visualize data quickly.
  • 📌 Use Case: Analyze revenue by product category.

💻 6. Learn Programming for Data Analysis

Python and R are the go-to programming languages for analysts.

🔑 Tools to Master:

• 🐍 Python Libraries: Pandas (data manipulation), NumPy (numerical computations).
  • 📝 Example: Analyze customer purchase frequency.
• 📘 R Libraries: ggplot2 (visualizations), dplyr (data wrangling).
  • 📌 Use Case: Create a trend analysis report for monthly sales.

🔍 7. Conduct Exploratory Data Analysis (EDA)

EDA is about uncovering trends and insights from data.

🔎 Techniques:

• 🛠️ Pattern Recognition: Look for seasonal sales trends.
• 🔥 Heatmaps: Identify correlations between variables.
  • 📝 Example: Correlate ad spend with sales growth.

💼 8. Build Business Acumen

Understanding the industry context is crucial for meaningful analysis.

💡 Tips:

• 📈 Domain Knowledge: Know metrics relevant to your industry, like Customer Lifetime Value in e-commerce.
• 🗣️ Data Storytelling: Present findings in a way that resonates with business leaders.
  • 📌 Use Case: Create a presentation showing how marketing campaigns improved ROI.

🌐 9. Collect and Source Data

Data analysts often need to find and pull data themselves.
