EVALUATION OF PSYCHOCORRECTION OF SOME PSYCHOLOGICALLY IMPORTANT PROFESSIONAL QUALITIES OF MARTIAL ARTISTS FROM THE POSITION OF R. FISCHER AND J. COHEN
In modern world science, especially in psychological research, in recent decades, there have been active disputes between supporters of evaluating the results of experiments using the values of "significance" by Ronald Fischer (1925) and "effect size" by Jacob Cohen (1962) - which of the parameters more accurately represents the results of the experiment? Our experiment and data processing showed that the "effect size" of Jacob Cohen is more preferable in psychological experiments in sports, since it reacts more subtly to the impact and places emphasis on those scales that are more exposed to psychotraining.
