Youwill take part in several data analysis assignments in which you will develop areport using tables and figures from the IBM SPSS® output file of yourresults. Using the resources and readings provided, you will interpret theseresults and test the hypotheses and writeup these interpretations.
 
Instructions
 
·       Copyand paste all tables and figures into a Word document and format the results inAPA current edition. 
·       Interpretyour results.
·       Finalreport should be formatted using APA current edition, and in a Worddocument.
·       4-5double-spaced pages of content in length (not counting the title page orreferences).
 
Thisassignment has three parts and uses the FloridaCounty Government. sav dataset. Load the data set into SPSS.
 

1.      Addressthe following research question using anindependent samples t-test:

 
RQ 3: Is there a significantdifference in the percent of total spending that is environmental spendingbetween coastal counties and non-coastal counties?
·       H03:There is no statistically significant difference in the percent of totalspending that is environmental spending between coastal counties andnon-coastal counties.
·       Ha3:There is a statistically significant difference in the percent of totalspending that is environmental spending between coastal counties andnon-coastal counties.
 
1.     Openthe data file Florida County Government.sav. 
2.     Performan error bar plot first. 
3.     Clickon Graphs/Legacy Dialogs/Error Bar. 
4.     Clickon Simple button and then radio button “summaries for groups of cases” thenclick on Define. 
5.     Moveto Variable box on the right the dependent variable Average % Envir. Spending in Total spending (AverageEnvirTotal). 
6.     MoveCoastal Area or Not to Category Axisbox.  This is the independent groupsvariable. There are two groups: coastal county=1 and not coastal county=0. 
7.     ClickOK.
8.     Edit theerror bar plot by adding data labels and title.
9.     Followdirections in Cronk and in the resources provided. What do you think from thatplot you would expect to find in an independent samples t-test?
10.  Now, perform an independent tsamples t-test with:
o  coastal (1)/non-coastal county (0) as your independent variable groupsand;
o  Average % Envir. Spending in Totalspending (AverageEnvirTotal) as your dependentvariable. 
11.  Use Cronk and resources provided tointerpret the results of the Levene’s test of assumed equal variances and theninterpret the t-test results and report based on the testing of yourhypotheses. 
 

2.      Addressthe following research question using a One-WayANOVA test:

 
RQ 4: Is there a significantdifference in the intergovernmental revenue growth rate (IGR) based on countytype (metro/suburban/rural)?           
·       H04:There is no statistically significant difference in the intergovernmentalrevenue growth rate (IGR) based on county type (metro/suburban/rural).
·       Ha4:There is a statistically significant difference in the intergovernmentalrevenue growth rate (IGR) based on county type (metro/suburban/rural).
 
1.     Openthe data file Florida County Government.sav.
2.     Performan error bar plot first.
3.     Moveto Variable box on the right the dependent variable intergovernmental revenue growth rate (IGR).
4.     Movecounty type (metro/suburban/rural) toCategory Axis box.  This is theindependent groups variable. There are three groups.
5.     ClickOK.
6.     Edit theerror bar plot by adding data labels and title. Follow directions in Cronk andin the resources provided. What do you think from that plot you would expect tofind in a One-Way ANOVA test?
7.     Now,perform a One-Way ANOVA test with:
o  Countytype as your independent variable groups and;
o  Intergovernmentalrevenue growth rate (IGR Growth rate) as your dependent variable.
8.     Runpost-hoc tests as well.
9.     UseCronk and resources provided to interpret the results of the Levene’s test ofassumed equal variances, interpret the One-Way ANOVA results, interpret theresults of post-hoc tests, and produce a report based on the testing of yourhypotheses.
 

 

3.      Adda covariate to your One-Way ANOVA and rerun as an ANCOVA.  The new research question is:

 
RQ 5: Controlling for politicalorientation (political), is there a significant difference in theintergovernmental revenue growth rate (IGR) based on county type(metro/suburban/rural)?
·       H05:Controlling for political orientation (political), there is no statisticallysignificant difference in the intergovernmental revenue growth rate (IGR) basedon county type (metro/ suburban/rural).
·       Ha5:Controlling for political orientation (political), there is a statisticallysignificant difference in the intergovernmental revenue growth rate (IGR) basedon county type (metro/suburban/rural).
 
1.     Performan error bar plot first.  What do youthink from that plot you would expect to find in an ANCOVA test? 
2.     Then,perform an ANCOVA test with:
a.     County type as your independent variable groups,political as your covariate, and;
b.     Intergovernmental revenue growthrate (IGR Growth rate) as your dependentvariable.
 
GeneralInstructions
 
Asdoctoral students, your assignments are expected to follow the principles ofhigh-quality scientific standards and promote knowledge and understanding inthe field of public administration. You should apply a rigorous and criticalassessment of a body of theory and empirical research, articulating what isknown about the phenomenon and ways to advance research about the topic underreview. Research syntheses should identify significant variables, a systematicand reproducible search strategy, and a clear framework for studies included inthe larger analysis.
 
Manuscriptsshould not be written in first person (“I”). All material should be 12-point,Times New Roman type, double-spaced with margins of one inch.
 
Allmanuscripts should be clearly and concisely written, with technical materialset off. Please do not use jargon, slang, idioms, colloquialisms, orbureaucratese. Use acronyms sparingly and spell them out the first time you usethem. Please do not construct acronyms from phrases you repeat frequently inthe text.
 
 
Structureof Assignment Paper
 
1.     Usethe following structure for your research article: Abstract, Introduction,Literature Review/Theory, Methods, Results, Discussion, and Conclusion.Include a robust discussion section distinct from your conclusion.
 
2.     Giveyour article a Title that is both descriptive and inviting toprospective readers. Your article title should appeal to both scholars andpractitioners. Use a shortened version of the main idea of your article in thetitle.
 
3.     YourAbstract should inform readers what your article is about and its mostimportant findings. Readers, including scholars and practitioners, should beable to understand your topic, argument, and conclusions. Make your abstractstraightforward and do not use technical language or jargon.
 
4.     Inthe Lit Review/Theory, cite only literature and theory pertinent to thespecific issue and not those that are of only tangential or generalsignificance. When summarizing earlier works, avoid nonessential details;instead, emphasize pertinent findings, relevant methodological issues, andmajor conclusions. Citation of relevant earlier literature is a  sign of scholarly responsibility and it iscritical for the growth of a doctoral student in public administration.
 
5.     Methods: The Methods section “describes indetail how the study was conducted, including conceptual and operational definitionsof the variables used in the study. Different types of studies will rely ondifferent methodologies; however, a complete description of the methods usedenables the reader to evaluate the appropriateness of your methods and thereliability and the validity of your results” (APA current edition).  Include a description of your sample size andprocedure, participants, how data collected, and research design.
 
6.     Results include data analysis used,results of the analysis including tables and figures.
 
7.     Discussion section includes interpretationsfrom the analysis. How do your analyses relate to the results found by scholarsin your lit review/theory section. In this section, evaluate and interprettheir implications, especially with respect to your original hypotheses.
 
8.     Providea distinct Conclusion that tells readers what you found, why it isimportant, and what difference it will make for research and practice. Ensureyou separate your discussion section from the conclusion of the article.Synthesize your article; do not summarize it. Show readers how the pieces ofyour article fit together. Answer the question “So what?” Why is your articlesignificant, and how is it relevant?
