Part 1: You have learned to compare several independent means and factorial design and now please answer the following questions in detail by applying the knowledge that you have gained from readings and lectures. It is important to include hypothetical examples whenever applicable. Make sure that in each of the following cases provide a hypothetical example.
● Describe the objective in single factor ANOVA and the underlying assumptions, formulation of the hypothesis, the sum of squared errors terms, the test statistic, the rationale for rejecting the null, the criterion for choosing the rejection region, possible test outcomes, and the criterion for evaluating the p value.
● Explain the objective in single factor randomized block ANOVA design and the underlying assumptions.
○ Explain formulation of the hypothesis, the sum of squared error terms, the test statistic, the rationale for rejecting the null, the criterion for choosing the rejection region, possible test outcomes, and the criterion for evaluating the p value.
● Explain the objective in two-factor ANOVA and the underlying assumptions.
○ Explain formulation of the hypothesis, the sum of squared errors terms, possible test outcomes, main effects and interaction effects.
A research firm tests the miles per gallon characteristics of three brands of gasoline. Because of different gasoline performance characteristics in different brands of automobiles, five brands of automobiles are selected and treated as blocks in the experiment; that is, each brand of automobile is tested with each type of gasoline. The results of the experiment (in miles per gallon) provided in Table.
The Results of the Experiment (miles per gallon)
I II III
Automobiles A 18 21 20
B 24 26 27
C 30 29 34
D 22 25 24
E 20 23 24
Use the sample data provided in the Table 8 to answer the following questions:
- Provide descriptive statistics of the data divided according to the division in gasoline brand.
- Formulate a single factor ANOVA hypothesis test, with gasoline brand being the factor.
a. Perform the test, interpret the result, and include all phases of ANOVA.
- Analyze the data using the ANOVA procedure for completely randomized designs and include all phases of the test.
a. Compare your findings with those obtained in question (a).
b. What is the advantage of attempting to remove the block effect?
- Perform post-hoc tests for rank ordering, if applicable.
Use ɑ = .05 in all tests. Perform the tests once manually and once using SPSS.
s regarding environmental issues as a threat but this do by a referent object in a specific social, political, linguistic structure. (Stritzel, 2007) The vague conceptualisation of the specific referent object as mentioned by the Copenhagen School – need the post-structural position created by the second generation of securitisation scholars where they stress the importance of the role the audience play along with setting the socio-political environment. (Salter, 2008) The purpose of this essay was to assess critically the strengths and weaknesses of the securitisation theory. After discussing the concept of the securitisation theory as conceptualised by the Copenhagen School, the essay went on to discuss how the theory was developed by second generation of securitization scholars by focusing on “what conditions the social content and meaning of security produced threats.” (Balzacq, 2010) The essay then went on to discuss the stance the Aberystwyth School had on the voice of the audience and finally, the idea of environmental securitisation was discussed. It can be argued that security may not be a negative practice, which as discussed above involves the use of hard power but instead the emancipation from the “relative objectivism” affecting both traditional stance on security and the Copenhagen School work. Therefore, it can be said that the concept of security can be revised to provide a unified position on security. In regard to the securitisation of environmental degradation, environmental issues can be tackled rather than those issues being exploited politically. This essay has provided a range of strength and weaknesses to the Securitisation theory.>GET ANSWER
