We consider 7 examples below: 1. A counselor wishes to compare the effectiveness of two types of counseling* (Rogerian and Adlerian) on changing the attitude of low achieving high school students toward school. She also has a control group in her study. Thus, there are 3 groups being compared on the dependent variable of attitude toward school. 2. A psychologist wants to determine if five drugs have a differential effect on reaction time (dependent variable) for 100 subjects, 20 of which have been randomly assigned to each drug.
Jones had administered the same math test to each of his two eighth grade classes, with the results shown below: Size Mean Class 1 20 60 Class 2 40 80 Mr. Jones then naively computed the average for all students by taking the average of the above two means, yielding 70. (a) Intuitively, why is this not correct? (b) The correct formula for finding the combined mean is to use a weighted average: xc = (n1 x1 + n2 x2 ) /(n1 + n2 ) where n1 and n2 are the respective group sizes and x1 and x2 are the group means.
