Wow, I read it again.  It's even worse than I remember.  It's clear that they took a look at the the data and chose a break point (20%) that would kind of support their agenda.  This wasn't a study, this was a data trolling expedition to find results they liked.  Even that wasn't particularly successful.  From the paper: &quot;In math, the cumulative positive effect of attending a green zone school by the end of elementary school (nine points, p&lt;0.12) was about the same as that of attending the lowest-poverty elementary schools (eight points, p&lt;0.05). However, in reading, the cumulative effect of attending a green zone school (eight points, p &lt;0.12 level) was larger than attending the lowest-poverty schools (five points, p&lt;0.20 level). &quot;

[b]They're touting results with p-values of .2.[/b]

That's because the study isn't about chemistry, it's about people, and people are statistically messy. That is well-known.

It's precisely because people are "messy" that tests for statistical significance are used.  [b]There's no need for p-values in chemistry[/b].  And if .2 is the best that they could "find" during analysis of the data post collection, then it's almost certain that there's no real correlation.[/quote]

Ooo! Ooo! I have to go tell my friends who are chemists! Won't they be interested![/quote]
