We stronglyrecommend you to refer to the Academic Learning Skills materials available in the Moodle. Fordetails please click the link http://moodle.kent.edu.au/kentmoodle/course/view.php?id=5 anddownload the file “Harvard Referencing Workbook”. Appropriate academic writing and referencingare inevitable academic skills that you must develop and demonstrate.We recommend a minimum of FIVE references unless instructed differently by your lecturer. Unlessspecifically instructed otherwise by your lecturer, any paper with less than FIVE references may befailed. Work that includes sources that are not properly referenced according to the “HarvardReferencing Workbook” will be penalised.Marks will be deducted for failure to adhere to the word count – as a general rule, you may go overor under by 10% than the stated length.GENERAL NOTES FOR REFERENCINGHigh quality work must be fully referenced with in-text citations and a reference list at the end. Werecommend you work with your Academic Learning Support (ALS) site(http://moodle.kent.edu.au/kentmoodle/course/view.php?id=5) available in Moodle to ensure thatyou reference correctly.References are assessed for their quality. You should draw on quality academic sources, such asbooks, chapters from edited books, journals etc. Your textbook can be used as a reference, but notthe lecture notes. We want to see evidence that you are capable of conducting your own research.Also, in order to help markers, determine students’ understanding of the work they cite, all in-textreferences (not just direct quotes) must include the specific page number/s if shown in the original.Before preparing your assignment or own contribution, please review this ‘YouTube’ video byclicking on the following link: Plagiarism: How to avoid itPLAGIARISM: HOW TO AVOID ITYou can search for peer-reviewed journal articles, which you can find in the online journal databasesand which can be accessed from the library homepage. Wikipedia, online dictionaries and onlineencyclopaedias are acceptable as a starting point to gain knowledge about a topic, but should not beoverused – these should constitute no more than 10% of your total list of references/sources.Additional information and literature can be used where these are produced by legitimate sources,such as government departments, research institutes such as the NHMRC, or internationalorganisations such as the World Health Organisation (WHO). Legitimate organisations andgovernment departments produce peer reviewed reports and articles and are therefore very usefuland mostly very current.

Explain how models are used to assist in analysing and modifying existing business systems

1. TIMELINES AND EXPECTATIONS. Your assignment will be assessed by your tutor or lecturer if your lecturer is also your tutor. You willreceive your mark and written feedback via Moodle two weeks after the due date or submission,whichever is later.2. INTRODUCTIONIn this assignment you will model the behaviour of systems or subsystems for two of your mostcomplex use cases using two UML diagrams (activity diagram and system sequence diagram) andwrite the extended use case description. You must also submit test plans and screens developedusing InVision.Section 3 describes the motivation behind the design of this assignment. Section 4 providesinformation on how and what to submit (note that Moodle has been setup so there is only onesubmission from each group). Section 5 explains the tasks for individual and group work. You willfind the criteria for marking your submission in Section 6.3. MOTIVATION.The purpose of the assignment is to ensure that you know:1. How to write extended use case texts.2. How to model the dynamic aspect of a system using UML (activity diagram and systemsequence diagram).3. How to develop screen prototypes to assist analysis.4. How to develop quality test plans.The assignment addresses the following learning outcomes:K1. Explain how models are used to assist in analysing and modifying existing business systems;K2. Define various roles involved in the processes of system analysis;K3. Describe techniques used to gather required information for system analysis;K4. Explain the various stages of the system development life cycle;S1. Identify appropriate models for given scenarios;S2. Develop various models using a professional CASE tool;S4. Perform Object Oriented Analysis and Design to construct various object models used tocommunicate the scope and requirements of the project.Page 2/5ITECH2002 – Systems ModellingAssignment 2 SpecificationA1. Write integrated reports, using appropriate models, providing detailed analysis of given textualscenarios.4. HOW AND WHAT TO SUBMIT• Moodle has been set up so each group submits only one document – anyone from a team cansubmit.• Submit a Word or text document which has the link to a GoogleDoc document which has thegroup work and individual work and the link to the top level InVision screen. This GoogleDocdocument must be complete: if it uses LucidChart, then please include the images drawn inLucidChart in GoogleDoc and provide the link to the LucidChart images. In other words, readersshould only need to read the GoogleDoc document without having to refer to LucidChart. Wewill check the history of GoogleDoc and InVision Screens to find out how much you havecontributed to this assignment. You must share the GoogleDoc, LucidChart and InVisionScreens with your lecturer and tutor.As a general guide to how the document should look, think about your target audience, which inthis case is another system analyst and a quality assurance (QA) team who will work with thesystem. Remember that everyone is busy and overloaded with information, so please include onlythe most essential information: be brief but clear. The QA team will use the test plans to developautomated system tests. We expect the GoogleDoc document to have the following information:1. The name of the organisation you are modelling.2. The name and student ID of each team member and the name of the system or subsystemmodelled.3. For each member, the extended use cases, activity diagrams, and system sequence diagrams fortwo of the most complex use cases.4. Snapshots of all screens, and a link to the top level Invision screen which links to the screen ofeach member. The screen for each team member must be from one of the two use casesselected in step 3.5. For each member, the test plan for the use case chosen in step 4 – in other words, the test planmust be for the same use case as for the screen design.

Develop a scatter diagram with GDP per capita as the independent variable. What does thescatter diagram indicate about the relationship between the two variables?

1ECONOMICS AND QUANTITATIVE ANALYSIS LINEAR REGRESSION REPORT

As an economist working in the OECD you have been asked to prepare a short report that examinesthe statistical association between average life satisfaction and GDP per capita using the datacontained in the spreadsheet (linear regression assignment data).Your report needs to be structured as follow:1. Purpose (2 marks)In this section, the purpose of the report needs to be clearly and concisely stated.2. Background (4 marks)In this section, a brief literature review on the association between life satisfaction and GDP isrequired. Why are economists interested in this particular issue?3. Method (4 marks)In this section, the data source and empirical approach used to examine the relationship between lifesatisfaction and GDP needs to be detailed.4. Results (20 marks)In this section, you need to present and summarize the results from your statistical analysis. Inparticular, the results section must:? Provide a descriptive analysis of the two variables (e.g., mean, standard deviation, minimumand maximum). Which countries have the lowest and average life satisfaction scores? Whichcountries have the lowest and highest GDPs per capita? (2 marks).? Develop a scatter diagram with GDP per capita as the independent variable. What does thescatter diagram indicate about the relationship between the two variables? (3 marks).? Develop and estimate a regression equation that can be used to predict average lifesatisfaction given GDP per capita. (2 marks).? State the estimated regression equation and interpret the meaning of the slope coefficient (tomake the interpretation easier multiply the estimated coefficient by 10,000). (3 marks).? Is there a statistically significant association between GDP per capita and average lifesatisfaction? What is your conclusion? (2 marks).? Did the regression equation provide a good fit? Explain. (3 marks).? Luxembourg, Ireland, and Norway appear to be outliers in terms of GDP per capita. Reestimateyour regression model without Luxembourg, Ireland, and Norway. How does thisaffect the slope coefficient and goodness of fit? Explain. (5 marks).5. Discussion (5 marks)In this section, provide a brief overview of the results. What are the key strengths and limitations ofthis analysis? (e.g., data, method, etc.). How do the results from this analysis compare with otherstudies? (e.g., are the findings consistent?). Do these findings have clear policy implications?6. Recommendations (5 marks).In this section, you should present three to five well-considered recommendations.Please ensure that your report is submitted as a single file.
