استخدام حجم الأثر في اختبارات (t)‎ وفق المنهج التجريبي ضمن بحوث علوم الرياضة "نحو تكامل بين الدلالتين الإحصائية و العملية"

الملخص EN

The study aims to clarify the importance of extracting the magnitude of the effect size in sports science research, especially those that use the experimental method, which is the method that uses the design of certain programs to reach an impact in the dependent variables, where the study focused on the correct concepts of effect size and practical significance besides The statistical significance and statistical power analysis, and how there is integration between them, as the study sought to clarify the imbalance in the case of neglecting the magnitude of the effect size in sports science research and how this may lead to misleading values that keep the researcher from issuing correct judgments according to a practical significance that supports the statistical significance in the judgment on the impact of the program We also tried to include the most important and most famous equations of effect size, which follow the testing of difference hypotheses using t-tests.
