RE: [tips] Polling...

One of my stat professors in grad school referred to it as the "inter-ocular trauma test". (If someone else said that already, never mind). :) Tim From: Claudia Stanny [mailto:csta...@uwf.edu] Sent: Tuesday, April 23, 2013 8:46 AM To: Teaching in the Psychological Sciences (TIPS) Subject: Re: [t

Although I referred to a quasi-experiment in an earlier post, I do not like the term. I teach it and try to explain how it is used. However, I also express my opinion that a study is an experiment or it is not. There are strict requirements for a true experiment and if they are not all met, the

Re: [tips] Polling...

      I agree with the eyeball method and it fits a distinction I always make between the context of discovery and a context of justification. Most researchers (some tipster might want to say "some researchers") discover based on the eyeball, playing with d

Re: [tips] p < .05, "reliable," and other highly significant things...

Watching this discussion, and seeing various people express their highly refined and delicate sensibilities about this use of this word, I begin to wonder whether something so incredibly arcane and fragile as statistical "significance" is really worth all the trouble. Perhaps we need a more robu

RE: [tips] Polling...

Dear Tipsters, Continuing on Claudia's lighter side, whenever we consider results in the research methods course (either from an article or one of our projects), I always ask the class to say what their eyeballs are telling them. Then we look at the stats to see if the eyeballs are correct or n

Re: [tips] Polling...

On the lighter side, one of my statistics professors liked to talk about the "inter-ocular effect": An effect so big it hit you right between the eyes (and the statistical analysis was a matter of confirming the obvious). :-) Claudia _ Claudia J. Sta

[tips] p < .05, "reliable," and other highly significant things...

Many thanks to all for the reassurance. I always tell my students, "significance" is like being pregnant: one either is pregnant or one is not; it does not admit of degree. (Although those of you who have borne children might disagree!) I also got some new ideas for how I might talk about som

Re: [tips] "Statistically reliable?"

Just a couple of points: (1) A statistically significant result has two interpretations: (a) The null hypothesis is true and the decision to reject it is a Type I error. (b) The null hypothesis is false and the decision to reject it is correct. In either case, one would want to calculate an
