Are these real data sets?

They are the real shapes of real phenomena, drawn cleanly rather than plotted from exact figures · so the curve for world population really is exponential, and the one for daylight really is a seasonal bell. The point is to learn the shapes, not the precise numbers.

There is no end · you simply build the longest streak of correct guesses you can. Each correct answer extends your streak; a wrong one resets it, and your best streak is shown.

Why does a phenomenon make a particular shape?

That is exactly what the game teaches. After each round it explains the shape in a line · why population grows exponentially, why adoption follows an S-curve, why deaths rise in winter, and so on.

Will I keep seeing the same questions?

The questions are shuffled and which side shows the real curve is random each time, so a run stays fresh even over repeats.

Does it work offline?

Yes. PlayMemorize is a Progressive Web App, so Which Curve keeps working without a connection once the page has loaded.
