WebPhi is the mean percent difference between party and vote with either considered as causing the other. Meaning of association: Phi defines perfect association as predictive monotonicity (see discussion in the section on association ), and defines null relationship as statistical independence. Symmetricalness: Phi is a symmetrical measure. WebEffect size is an essential component when evaluating the strength of a statistical claim, and it is the first item (magnitude) in the MAGIC criteria. The standard deviation of the effect size is of critical importance, since it indicates how much uncertainty is …
The term phi phenomenon is used in a narrow sense for an apparent motion that is observed if two nearby optical stimuli are presented in alternation with a relatively high frequency. In contrast to beta movement, seen at lower frequencies, the stimuli themselves do not appear to move. Instead, a diffuse, amorphous … See more Wertheimer's classic experiments used two light lines or curves repeatedly presented one after the other using a tachistoscope.
