Is It Real?
📋 What it is
A small sample is noisy: with few data points, luck (variance) can look like a real trend. Bigger samples are steadier.
🗣️ Coach says
Two posts did great, so "posting at 8pm works"? Two posts is nothing — that could be pure luck. Real patterns need enough data to rule out chance. Ask: is this a TREND, or did I just flip heads twice?
🧠 Memory hook
Small sample = noisy. A "trend" from a handful of posts might just be luck.
😂 Giggle
What did the algorithm say when it finally learned?
"Now I recommend myself a nap!"
😲 Whoa!
Flip a fair coin 4 times and getting 4 heads happens ~6% of the time — small samples throw "amazing streaks" constantly.
✅ Quick check: You post twice at 8pm and both do well. Is "8pm is my best time" a safe conclusion?
Say your answer out loud first — then reveal.
No — two posts is too small a sample; that could easily be luck. You need many more posts to tell a real pattern from noise.
Judging sample size stops you from chasing a "trend" that is really random variance.
