Principle 6: Select and Analyze Dataset Like a Pro

 Why Multiple Datasets = Strategic Advantage 

Working with multiple datasets isn’t just a backup plan – it’s a powerful methodology to ensure your IA stands out. Here’s why: 

  • Reduces risk of “dead-end” analysis 
  • Uncovers unexpected patterns through comparison 
  • Demonstrates critical thinking in dataset curation 
  • Helps avoid confirmation bias 

The 3-Step Dataset Strategy 

Step 1. Gather or create 2-3 datasets, either from the same category or different ones, to enrich your analysis.

Example: possible dataset options for a Sports IA

  • Team Season Stats: Compare stats like points scored or win rates for 2-3 different teams.
  • Player Biometrics: Analyze heart rate or sleep logs for players from 2-3 different teams.
  • Social Media Engagement Metrics: Measure likes, shares, or comments for 2-3 different teams.

Step 2. Perform Initial Analysis on All Datasets 

  • First Dataset: Establishes methodology (slowest phase) Example: Cleaning raw sales data, defining variables 
  • Subsequent Datasets: Reuse code/tools from first analysis (70% faster) Example: Apply same regression model to climate data 
  • Pro Tip: Use a master analysis template in Excel to automate repetitive tasks.

Step 3. Select the "Golden Dataset"

Case Study: Pizza Delivery IA 
  1. Dataset A (Corporate Chain): Clean but bland correlations 
  2. Dataset B (Local Shop): Messy but shows weather impact 
  3. Dataset C (Your Delivery Job): Reveals tipping patterns by neighborhood 
  4. Winner: Dataset C – unique personal angle + socioeconomic insights
