Play with the numbers. Distrust them.
Statistics gets more interesting when we can touch the data, test a hypothesis and discover what the chart is hiding.
Experiment 01 · Probability
The mystery of the 23 birthdays
With 23 people in a room, the chance that at least two share a birthday is over 50%. The secret is that there are 253 possible pairs. Try changing the size of the group.
Experiment 02 · Game
How many loaves, Seu Joaquim?
Seu Joaquim, a baker, has to decide how many bread rolls to bake. Leftovers are waste; running out means lost sales and complaints. In four stages — gut feeling, history, forecasting and marketing — the game shows how data helps decide under uncertainty, without eliminating it.
The lab does not stop here
From surprise to investigation.
In upcoming experiments we will work with moving charts, public data, football, the environment, statistical comparisons and seemingly impossible stories.
