I have a lovely romantic view of olden days scientists – perhaps better described as naturalists – way back in the days of yore merrily going about recording observations and collecting specimens.
But such an approach doesn’t really cut it if you’re serious about collecting data, and convincing others that you’ve answered a real scientific question.
What you need at the outset is a hypothesis. If you’re being really detailed, a null hypothesis works even better.
But what are these things, and how do they make science so sturdy? And how can we be confident the results of a study are good?
Perhaps you’d better watch the latest TechNyou animation to find out: This Thing Called Science Part 4: Confidently uncertain (produced by Bridge8).
