Karin believes that students with behavior problems react best to teachers who have a humanistic philosophy and have firm control of their classrooms. In a large city school system, she classifies 40 high school teachers of students with behavior problems into three categories: humanists with firm control (group 1, n = 9); strict disciplinarians (group 2, n = 21), and Laissez-faire (or keepers of the behavior problems; group 3, n = 10). Karin is interested in assessing whether students who are taught by one type of teacher as opposed to another type of teacher are more likely to stay out of difficulty in school. By reviewing the records of all students in these 40 teachers' classes, she determines the number of times the students of each teacher were sent to the main office for disciplinary action during the second half of the academic year.

The data, A4.sav, are from Karin's research problem involving students with behavior problems and different teaching styles. Using a one-way ANOVA (Welch's F test) to answer Karin's question and write a Results section (including a APA formatted table for descriptive statistics, such as sample sizes, means, and standard deviations) based on the analyses conducted
