Mean (The Balancer)

The mean is like finding the balance point of all the numbers.

• Add up all the numbers
• Divide by how many numbers there are
  
  It’s great for getting an overall sense, but can be thrown off by extreme values.

Example: Test scores: 80, 85, 90, 95, 100
Mean = (80 + 85 + 90 + 95 + 100) / 5 = 90
