Grade: grade 1-2 grade; reference comes from Hovland. 1949:Unpaged) has proposed the effectiveness index (Effectiveness Index), which result from the contrast of the.Before the test, the tried-and-tested after the experiment with the highest score that can be done increases.Hovland has proposed that the value of the relationship, the trial will be performed properly, certainly.Despite the difference of score (test score prior to the study, and the points can be.Maximum of The effectiveness index determines the scope and effectiveness of Webb media attention.The average percentage score, which learn from the percentage of the Group experiment and find the percentage of control group.The results will show the percent increase (or decrease) compared with the control group's index score.There are productive in finding patterns.
