Interactive — learn by doing. Drag, tap and explore to build the intuition.
Average is the balancing level
Drag any bar. The dashed line (the mean) always settles where the amounts poking above it exactly fill the gaps below.
40
55
30
75
50
(40 + 55 + 30 + 75 + 50) ÷ 5
average = 50
Change one bar by +10 and the average rises by just 10 ÷ 5 = 2 — the change is shared across all 5.
💡 Replacing a value shifts the total by the difference, so the average moves by (difference ÷ count).
