Effect size is an estimate of the degree (magnitude) to which: a. There is a difference between two independent variables b. The magnitude of the independent variable/treatment effect the dependent variable in an experiment The dependent variable effect on the independent variable in the experiment d. None of the above Given a Psychology researcher is testing a New Anxiety Therapy versus the Gold Standard-the typical Anxiety Therapy, and the researcher's hypothesis is that the New Anxiety Therapy will result in faster healing (measured in weeks) versus that of the Gold Standard Therapy. The Null Hypothesis would be: a. There will be no significant differences between the two Therapies regarding number of weeks to heal b. There New Anxiety Therapy will result in few weeks to heal vs the Gold Standard therapy The New Anxiety Therapy will result in more weeks to heal vs the Gold Standard therapy d. The effect size between therapies will be very large
