The article does state that the difference is statistically significant: "Curiously, the musician group seemed to select the 16-bit dithered Vivaldi as the "better" sounding version (p-value 0.047)."
- ZoFreX 12y agoI'm not convinced it is, though. If you take a sample of 140 people and divide it into a dozen different cohorts, it's pretty likely that one of those groups will show a difference that would be statistically significant if observed across the whole sample.
- Steuard 12y agoHow many individual comparisons were made throughout the article? A dozen? Two? You'd expect a p-value less than 0.05 by chance about one time in 20, and indeed this p-value is just marginally below that threshold. I wouldn't view this one result as particularly significant in that context.
