Definition

Data is a collection of recorded observations or measurements used to describe, analyze, or make inferences about a phenomenon or population.

💡 Intuition

Data is raw material for understanding—numbers, words, or categories we collect to answer questions.

🎯 Core Idea

Data without context is just noise; data with questions becomes insight.

Example

Survey responses, temperature readings, test scores, customer reviews—all are data.

🌟 Why It Matters

All statistical reasoning starts with data collection and understanding what data represents.

💭 Hint When Stuck

Ask: what question am I trying to answer? Then ask: what information would I need to collect to answer it?

🚧 Common Stuck Point

Data quality matters—bad data leads to misleading conclusions.

⚠️ Common Mistakes

Treating all data as numerical — categorical data (colors, yes/no) requires different analysis methods
Assuming more data always means better conclusions — biased or poorly collected data can mislead regardless of volume
Analyzing data without understanding how it was collected, leading to invalid conclusions
