Raftery, A.E. and Hout, M. (1985). Does Irish education approach the meritocratic ideal? A logistic analysis. Economic and Social Review, 16, 115-140.

To determine whether there is a relationship between the type of school attended and verbal reasoning scores for Irish students, three samples with 25 students, in each group, were randomly selected from data used by Raferty and Hout (1985). One group of students attended secondary school, the second group of students attended vocational school, and the third group consisted of students who attended only primary school.

If we let µ1, µ2, and µ3 be the mean verbal reasoning scores for students who attended secondary school, vocational school, and primary school only, respectively, the appropriate hypotheses in this case are:
H0: μ1 = μ2 = μ3
Ha: μ1, μ2, μ3, are not all equal
H0: μ1, μ2, μ3, are not all equal
Ha: μ1 = μ2 = μ3
H0: μ1 = μ2 = μ3
Ha: μ1 ≠ μ2 ≠ μ3
H0: μ1 ≠ μ2 ≠ μ3
Ha: μ1 = μ2 = μ3
None of the above are correct. Here are the three sample standard deviations for the verbal reasoning scores for the three groups (secondary school, vocational school, and primary school only):
Based on this information, do the data meet the condition of equal population standard deviations for the use of the ANOVA?
Yes, because 14.18 - 11.71 < 2. Yes, because 14.18/11.71 < 2. No, because the standard deviations are not equal. Unable to determine from the information provided. The analysis was run on the data and the following output was obtained:
Based on this information, we :
Fail to reject the H0 and conclude that the data provide strong evidence that the three mean verbal reasoning scores (representing the three types of schools attended) are not all equal. Fail to reject the H0 and conclude that the data do not provide sufficient evidence that there is a relationship between the type of school attended and verbal reasoning scores for Irish students. Reject the H0 and conclude that the data provide strong evidence that there is a relationship between the type of school attended and verbal reasoning scores for Irish students. Reject the H0 and conclude that the data provide strong evidence that verbal reasoning scores are related to type of school in the following way: the mean verbal reasoning score for Irish students who attended secondary school is higher than the mean verbal reasoning score for Irish students who attended vocational school, which in turn is higher than that of Irish students who attended only primary school.

Should pit bull terriers be banned in my community

 Discussion Forum: Counterarguments (Should pit bull terriers be banned in my community) You created a question about the topic for your W6 Rough Draft. For this discussion, you will give an answer to that question in the form of a thesis statement. "Dieting Makes People Fat" Main Post: Share your thesis statement with your classmates. Please note: As with last week’s discussion, nothing here is set in stone. Be open to changing everything about your topic, including your position and audience, as you research it and get feedback from your classmates. Topic + Position/Purpose + Supporting Points =Thesis Statement Example: Suppose the question you posed in the Week 5 discussion was something like, “Should pit bull terriers be banned in my community?” After doing some preliminary research, you have concluded that pit bulls, if raised properly, are no more dangerous than other breeds of dogs. Your thesis statement can be something like, “Pitbulls should not be banned

Controversy Associated With Dissociative Disorders

 Assignment: Controversy Associated With Dissociative Disorders The  DSM-5-TR  is a diagnostic tool. It has evolved over the decades, as have the classifications and criteria within its pages. It is used not just for diagnosis, however, but also for billing, access to services, and legal cases. Not all practitioners are in agreement with the content and structure of the  DSM-5-TR , and dissociative disorders are one such area. These disorders can be difficult to distinguish and diagnose. There is also controversy in the field over the legitimacy of certain dissociative disorders, such as dissociative identity disorder, which was formerly called multiple personality disorder. In this Assignment, you will examine the controversy surrounding dissociative disorders. You will also explore clinical, ethical, and legal considerations pertinent to working with patients with these disorders.
