Statistical Distributions
📋 What it is
A distribution shows how often each value occurs; many natural datasets form a bell shape.
🗣️ Coach says
A distribution is the shape of your data — which values are common, which are rare. Lots of natural things (heights, test scores) pile up in the middle and thin out at the edges: the famous "bell curve".
🧠 Memory hook
A distribution = the SHAPE of the data. Many pile up in the middle (a bell) and thin at the edges.

What did the probability say to the certainty?
"You're a 1 in a million... actually, exactly a 1."
😲 Whoa!
Human heights form a near-perfect bell curve — most people cluster near average, with very few extremely short or tall.
✅ Quick check: In a bell-shaped distribution, are most values near the middle or at the extremes?
Say your answer out loud first — then reveal.
Near the middle — the peak of the bell holds the most common values.
A bell curve concentrates data around the average and tapers at the ends.
🧪 Try it! (2 minutes)
Measure 10 friends' heights and plot them. Do they pile up in the middle like a bell?
