How to Calculate Averages Without a Tool

Calculating Mean

  1. Add all numbers together
  2. Count how many numbers you have
  3. Divide the total by the count

Finding Median

  1. Put numbers in order
  2. Find the middle number
  3. For even counts, average the two middle numbers

Determining Mode

  1. List all numbers
  2. Count how many times each appears
  3. The number with most counts is the mode

Advanced Average Calculations

Weighted Average

Some numbers count more than others.

Formula:
(Number₁ × Weight₁) + (Number₂ × Weight₂) + … ÷ Total Weights

Example:
Test 1 (30% weight): 80
Test 2 (70% weight): 90
Calculation: (80×0.3) + (90×0.7) = 24 + 63 = 87

Moving Average

Shows trends over time.

How to calculate:
Take averages of smaller groups in a larger data set.

Conclusion
