Publish or Perish (the p value)

I created this video about the ongoing, for years now, issue of the p value and its misuse. Actually I am not convinced it has any practical uses in a research article except maybe to tell the reader if you had enough participants or not.


If you want to know more about the uselessness of the p value read articles like:


Cohen, J. (1994). The earth is round (p < .05). American Psychologist, 49, 997-1003.

Schmidt, F., L, & Hunter, J. E. (1997). Eight common but false objections to the discontinuation of significance testing in the analysis of research data. In L. L. Harlow, S. A. Mulaik & J. H. Steiger (Eds.), What if there were no significance tests? (pp. 37-64). London: Lawrence Erlbaum Associates.

Lecture

I gave a lecture, The Cult of Significance Testing, on this issue using the video above to highlight the key issues.
