🧩 Why Median Matters
Median is less affected by outliers than mean. It’s used for income data, house prices, and test scores when there are extremes.
🎯 How Abacus Teaches Median
Order beads: Arrange rows from shortest to longest. Find middle row: For odd count, pick centre. Average for even: Add two middle rows, divide by 2. Practice: “Median of 1, 4, 6, 9, 12?” (6). “Median of 3, 7, 2, 10?” (order 2,3,7,10 → (3+7)/2=5).
💡 A Parent’s Example
“My son’s test scores were 85, 90, 65, 95, 80. He ordered them: 65,80,85,90,95. Median = 85. He understood that half were above, half below.”
You might wonder, “Why not just use average?” Median ignores outliers — useful for salary data where a few high earners skew the mean.
