Yes, but if we'd drawn only one blue and nine orange, that would have been much less likely if the proportions were equal.
voice-verified
And then we'd be able to say that there are more orange Smarties.
voice-verified
And our conclusion is said to be statistically significant at the 5% level.
voice-verified
And the real world relevance of this kind of test is pretty clear.
voice-verified
Those are great.
voice-verified
Let's say that instead of Smarties... Will you stop eating them, Tim?
voice-verified
Sorry.
voice-verified
Instead of Smarties, you're giving some people a new medical treatment and some people an old treatment.
voice-verified
Statistical significance is a test that assumes the treatments are the same and then looks for evidence that, in fact, they are not the same.

More or Less is presented by Tim Harford, the Financial Times' undercover economist.
voice-verified
The More or Less team is Richard Varden, Richard Knight, Wesley Stevenson and me, Hannah Barnes.
voice-verified
More or Less is made in association with The Open University.
voice-verified
Yeah, notably from Ian Duncan-Smith, the Work and Pensions Secretary.
voice-verified

voice-verified

voice-verified
And they're put into one of three categories, employed, unemployed or economically inactive.
voice-verified
And those definitions are suggested by the International Labour Organisation, which is a UN agency.
voice-verified
But the problem is, when they're applied to full-time students, it can lead to some quite strange results.
