Figure 1 shows the average for the dependent variable and label for one of the groups groups. In order label for the other group to test the difference in between and dependent variable label for one of the groups a label for the other group was conducted. The type of statistical test analysis revealed that those who received the active drug experienced (a similar number of, significantly more, significantly less) panic attacks (M = SD = ), compared to those who received the placebo mean st. dev (M= SD = ), with a mean difference of t ( mean st. dev mean difference df actual t-value P= 95% CIL 1, d= p (sig) value lower CI, upper'CI Cohen's dSuppose you have created a new anti-anxiety medication that treats panic attacks. You conduct a study, and randomly assign individuals with panic disorder to either receive the new anti-anxiety drug (Drug Condition), or to receive a placebo (Placebo Condition). The data show the number of panic attacks (dependent variable) individuals have experienced over the last 6 months since the trial began. Group Statistics Sid. Ener Group Maan End.
