Statistical Data

🔹 What Is It?

Statistical data is information that we collect, organize, and study to find patterns or answers to questions.

You can:

• Collect data (like test scores, heights, or survey answers)
  
  

• Display it (in tables, line plots, histograms, or box plots)
  
  

• Analyze it using measures like:
  
  

  • Mean (average)
    
    

  • Median (middle value)
    
    

  • Mode (most common)
    
    

  • Range (difference between high and low)
    
    

🧩 Clue to Remember

Statistics is about spotting trends and making sense of numbers.

🔹 Example

Test scores: 60, 70, 70, 80, 90

• Mean = 74
  
  

• Median = 70
  
  

• Mode = 70
  
  

• Range = 90 minus 60 = 30
  
  

💡 Why It Matters

Statistics helps you make decisions using data, whether you're comparing sports stats, analyzing science results, or making predictions.
