However, it seems like a lot of experiments wouldn't allow for single blind, since things like testing teacher performance pay would require the teachers know they are not receiving the status quo.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7464708.post-5393339904255602882012-03-18T20:52:59.942-04:002012-03-18T20:52:59.942-04:00How many bazzillion person hours and dollars may h...How many bazzillion person hours and dollars may have been pissed away on top-down interventions based on flawed methodology and claims?

Applied to a test or experiment conducted by one person on another in which information about the test that may lead to bias in the results is concealed from both the tester and the subject until after the test is made;" so, it's "tester and subject" that makes it double blind. I say the tests referred to are "single blind" if the farmer doesn't know what seed he's getting and "eyes wide open".Dougnoreply@blogger.comtag:blogger.com,1999:blog-7464708.post-91595819688800467372012-03-18T14:05:10.451-04:002012-03-18T14:05:10.451-04:00What about when the researchers do not know who is...What about when the researchers do not know who is getting the cool seed or the fake seed?Anonymousnoreply@blogger.com
