Recent research Indicates that the effectiveness of antidepressant medication is directly related to the severity of the depression (Khan, Brodhead, Kolts & Brown, 2005). Based on pretreatment depression scores, patients were divided into four groups based on their level of depression. After receiving the antidepressant medication, depression scores were measured again and the amount of improvement was recorded for each patient. The following data are similar to the results of the study. High Moderate Moderately Severe Low Moderate Severe 2.6 2.2 0.9 3.7 1.2 1.5 4.1 2.4 1.2 1.9 1.5 3.2 1.5 2.6 5.5 2.3 3.1 3.4 4.1 3.3 1.4 2.6 5.2 From this table, conduct an one way ANOVA. Calculate the F-ratio and p-value. Be sure to round your answers to three decimal places. Assume oll population and ANOVA requirements are met. F-ratio: p-value: What is your final conclusion? Use a significance level of a 0,02. O There is sufficient evidence that there exists a significant difference between treatments. O There is not enough evidence to determine a difference between the treatments. Submit Ouestion
