F and MinF' computations
Posted on août 25, 2000 in stats
Given by subjects and by items F values, this program computes MinF' (see Herbert H. Clark (1973) The LanguageasfixedEffect Fallacy: A critique of Language Statistics in Psychological Research in Journal of Verbal Learning and Verbal Behavior, 12, 335359.).
There would be an applet here if your browser supported java. Notes:

Press ENTER (or CtrlENTER) to move from one cell to the next (or to the previous).

It is possible to enter only one F value to compute its associated probability.
3.. A bug was corrected on Nov 17, 2005: the computed pvalue was wrong when the Fvalue was less than 0.5. Hopefully, it is now correct. (thanks to Arnout Koornneef and Timothy Desmet for pointing out the bug). This should not have created problems given that F<0.5 is quite far from the usual significance threshold...
 I am not advocating the use of MinF' !!! (I wrote this applet many years ago to train myself in Java). It may be better to use a mixed effect model approach considering both subject and items as random factors (See, e.g., Baayen, R.H., Statistics in Psycholinguistics: A critique of some current gold standards. In Mental Lexicon Working Papers 1, Edmonton, 145)
