A research clinic is interested in understanding the impact of a new anti-anxiety medication. They conduct a study to determine if there is a difference in anxiety scores (on a scale of 0 to 100) among participants who take the new medication, a traditional medication, and placebo. A random sample of study participants were assigned to one of three groups: new anti-anxiety medication (38 participants), traditional anti-anxiety medication (36 participants) and placebo (39 participants). Is there evidence to conclude that there is a difference among the three groups in terms of average anxiety scores? What statistical procedure should be used to answer this research question?
