Mean, Median, Mode, Range

🔹 What Is It?

• Mean is the average
  
  

• Median is the middle number
  
  

• Mode is the most frequent
  
  

• Range is the difference between highest and lowest
  
  

🧩 Clue to Remember

Mean: Add and divide
Median: Line up and find the middle
Mode: Most often
Range: Max minus min

🔹 Example

Set: 4, 6, 6, 7, 8

• Mean = (4 + 6 + 6 + 7 + 8) ÷ 5 = 31 ÷ 5 = 6.2
  
  

• Median = 6
  
  

• Mode = 6
  
  

• Range = 8 − 4 = 4
