The Difference Between Significant and Not Significant is Not Statistically Significant

MINDLESS SIGNIFICANCE TESTING

Decision science news has a post on hypothesis testing that I find relevant.

Some well-made points grow old while no one pays attention to them. One of the most embarrassing for social science is its categorical perception of p-values.

Tender of kindred Web site Andrew Gelman and Hal Stern have an article whose name says it all: The Difference Between “Significant” and “Not Significant” is not Itself Statistically Significant.

Writing: granularity

December 4th, 2006 by jose

There is an invited post over at  by Michael Leddy, an English professor who recommends that we should divide major actions (such as “write term paper”) into smaller, more doable tasks (NAs in GTD’s parlance). I think this could be a good read for students, and even for academics; Most of us keep this partitioning into smaller tasks “in our heads”; making it explicit and dumping it into paper might help with things such as time estimation… a consistent problem I have is that I never know how long I will need to finish a paper. This is one of the reasons I posted before that we need to decompose tasks to be able to track progress better.
