Hearing about your expertise an administrator comes to you. He is conducting a school-wide study to determine the difference across three programs in the combined graduate students 'perception of the School of Education climate and in satisfaction with their academic programs. His sample comprises four randomly selected groups of graduate students from these programs: school counseling, school psychology, and program evaluation students. He remembers something about p = .05, but has had basic statistics in the years prior to your birth. He is grateful for your advice. He collects his data and has his assistant put it into SPSS. You get an e-mail from his assistant; "OMG! My boss asked me about testing a null andsomething aboutassumptions. I do not assume anything. Please tell me what he is talking about."

1. What null hypotheses am I testing?
2. What are the assumptions and how do I test for them?
3. He said something about violating assumptions. I am a good person, I think. I don't do violations. What do I do if the assumptions are violated?
4. He also talked about skew or skewness and said that could be a problem if the data are skewed. Is it always a problem, what criteria do I use and what can I do if data are skewed? Please EXPLAIN.
