- 1. Data Analysis Research Report Assessment BSB123 Data Analysis BSB123 Data Analysis Notes on the Assessment Covers Topics 1 – 10 i.e. descriptive statistics to Multiple Regression Assignment is based around the international student recruitment industry looking specifically at students interested in postgraduate studies in USA All 500 observations on spreadsheet are for international students Variables are all related to factors which affect chance of being admitted and your job is to analyse this so that the company (GES) can advise future students about what to do and what their chances are of being admitted. Report is split so that in each section you look at different aspects You will need to do a summary incorporating elements of all of the parts to make recommendations. Marks reflect (generally) the amount of work you need to do.

Can you select the correct technique / analysis to solve the question Is that technique correctly and FULLY applied with calculations done correctly E.g. in a hypothesis test, did you: Correctly identify the test statistic (Z, T, F, χ2) Did you include accurate hypotheses and decision rule which are consistent with each other Were the calculations correct Did you check to see if the assumptions or conditions of the test held OR for Descriptive Statistics did you: Consider all aspects of how you describe data and use the appropriate statistics to do that Choose correct graph(s) for the type of data Summarise the results to actually describe what you found – not just quote the stats. Can you interpret the results – not just make a decision or complete a calculation. Can you express the result in terms of the question and in a way which is understandable to your audience In other words you will not get full marks unless you can correctly select the right approach to take for the data given,

- 4. P-value – what is it? 6 Hypothesis Test State the Hypotheses in terms of the parameter (µ,σ,p) Identify the correct probability distribution (t, z, F, χ2) Identify level of significance State decision rule clearly Use either test statistic method (i.e. in terms of t or z etc) or in terms of p-value. Don’t need to do both. Decision rule must be consistent with hypotheses Do calculations Use either Excel to get solutions where available Do the calculations to get test statistics e.g. tcalc or zcalc Make the decision in terms of the question Check if the conditions of the analysis hold – i.e. did you do a valid test BSB123 Data Analysis BSB123 Data Analysis Regression Conduct a regression analysis to determine which factors affect a students chance of admission. In undertaking the analysis do this in three steps: Regress all variables and conduct all tests necessary to determine which variables should be included in an optimal model. Re-estimate your chosen model from a. Interpret all necessary statistics and conduct all necessary tests. State your estimated equation and interpret the coefficient of the first and last variable you have included. Use the estimated equation to predict the chance of admission for a Male student from Brazil with a CGPA of 8.5, a TOEFL of 110, a GRE of 320, no letter of recommendation, an interview score of 15 and
- 5. who came from a mid rated (level 3) university which did not require a research project. (20 Marks) BSB123 Data Analysis BSB123 Data Analysis Regression Process Consider the explanatory variables to determine which are likely to affect the dependent variable of interest. This can be done by: Considering the theoretical logic of whether a variable is sensible Graphing X against Y to see if they are related linearly Looking at the correlation matrix (multiple regression) State the model to be estimated including expectations What is Y, what is X1, X2 etc and what would you expect to be the direction of the relationship Determine the strength of the relationship Test separately the overall significance of the model and each of the individual variables included State and test the assumptions of the model Clearly articulate which variables are useful or not, and why and then redefine the model using those you believe should be included. Compare results of new model to old by redoing all previous steps 2 - 6. Once final model is determined you can state and interpret estimated equation and use it to predict (if required).

- 6. Analysis and Summary Report Last Semester Write a brief report to management describing what you have found in non-technical language. The report can be no longer than 250 words. Include any recommendation you would like to make about income determination and hiring practices. Student 1 – Weak Answer It was determined that GPA is of clear importance as it has an undeniable importance in the determination of income for new and existing employees. Gender presents an issue as a current social issue is to ensure equal pay for all genders. Our analysis has indicated that the male staff are earning an extra $2000. This is an issue as it doesn’t present the equal pay requirement. Additionally, it was found that as your staff’s age increases, their salary increases at approximately $770 per year. Furthermore, this is in line with the generally accepted increases in wages as per general wages awards. (Note this student concluded in an earlier question that age was not an important factor!) Student 2 – Stronger Answer. There was insufficient evidence to conclude that there is any difference in the performance on the company test between males and females. However, there is evidence to show that despite males not seeming to outperform females, they are paid significantly more (just over $5000). (All statements are consistent with earlier analyses) What I was looking for In terms of remuneration there is evidence that males are being paid more than their female counterparts possibly even more than $5000 on average. Other tests have indicated there is no difference in performance between the genders in terms of
- 7. results on the test and job performance. While other tests have shown that job performance (Test scores), higher degrees and age all effect income (as expected), given there is no difference in job performance this is an area of inequality which needs to be addressed. It does not seem to be a recruitment issue with equal numbers of males and females employed, so it is a remuneration issue. BSB123 Data Analysis BSB123 Data Analysis Hints Check for consistency. If you do something in regression that overlaps with something you did earlier are the results the same. IF not, does that represent an issue? If we can’t see how or why you have done something, then we don’t know if you are thinking correctly. Even if you use Excel just show the output or briefly describe what you did. You have weeks to do this assessment so presentation shoul d be professional and terminology accurate. This is not a small assessment – it will take time. Don’t leave it until the last weekend. Use consultation this week and next to ask questions. We won’t answer specific questions on the research report, but you can be clever in how you ask questions which might lead us to give appropriate direction. A great deal of the work done on the research report will be repeated in the exam. This is a good chance to practice for the major assessment item.

- 29. China and Malaysia combined accepting hundreds of thousands or international students each year. This is particularly true in the post graduate education space. Globally there are many companies that act as agents for international students wanting to gain admissions to programs in other countries. Global Education Services (GES) is one such company and it is paricularly interested in the most important factors impacting admissions to graduate programs in the United States. GES collected data on 500 students, which they then provided to admissions offices across a range of institutions for a response on the likelihood of admission. Responses from the various universities were gathered and used to determine a Chance of Admission score for each student. Information was collected on 10 variables with a snapshot of the data set provided in the table below. Note the full data set which you should use is given in the Excel Spreadsheet provided: · Chance of Admit - % rating with the higher the number the greater the chance of acceptance · GRE Score – US college entrance score · TOEFL Score – English language test score · University Rating – Rating assessment of the university in which the student did their bachelor’s degree – 5 is highest. · Interview Score – out of 20 · Letter of Recommendation – Yes or No · CGPA – Adjusted Bachelors GPA out of 10 · Research – did the Bachelo’rs degree require a research project, Yes or No · Gender – Male or Female
- 30. · Region – Did student come from a nearby Region - Americas or Other You have been asked to provide a report to GES on the most important factors in obtaining admission in order for them to better advise students GRE Scores Globally the mean GRE score is 306 with a standard deviation of 11. Global Education Services (GES) believes that international students are a special group when it comes to GRE. Whereas every US student interested in entering graduate programs will undertake the GRE, International students are more selective because they have to pay for applications and hence they need to be more confident about their results. As such GES is of the opinion that international students are likely to have a better performance on the GRE and a more consistent one. 1. Describe in detail the GRE results for international students using appropriate numerical and graphical methods. (7 Marks) 2. Conduct a test to determine if the average GRE result for international students is higher than the global mean of 306. (5 Marks) 3. Conduct at test to see if the consistency of international students on the GRE is better than the global average – i.e. the variance is lower. (5 Marks) 4. It is reasonable to expect that performance on the GRE and the Chance of Admission would be related to each other. Construct a graph relating GRE and Chance of Admission and calculate an approriate statistic to help describe the relationship
- 31. between the two variables. Briefly describe the relationship. (5 Marks) 5. Based on Questions 1. to 4. briefly indicate if you believe GES’s opinion of International Student performance on the GRE is correct including the reason why. (3 Marks) Projects As countries have moved to increase the number of students undertaking Bachelor Degree programs pressure has come on many institutions to reduce or remove the major research project requirement for students at undergraduate level. 6. Construct a 95% confidence interval for the proportion of universities which now require a major research project for graduation. If 60% of universities used to require a research project what does this imply about the proposition that institutions are removing the research requirement. (5 Marks) 7. Conduct a test at the 5% level of significance to see if the proportion of universities requiring projects has fallen. (5 Marks) 8. Compare the results in part 6. and 7. Which is the better result to use and why. (2 Marks) Chance of Admission 9. While we would hope that there was no bias in admissions test at the 10% level of significance if the average chance of admission is different between Males and Females. Make sure you undertake all checks and tests necessary in order to be able to conduct this test. (8 Marks) 10. Conduct a regression analysis to determine which factors affect a students chance of admission. In undertaking the analysis do this in three steps: a. Regress all variables and conduct all tests necessary to
- 32. determine which variables should be included in an optimal model. b. Re-estimate your chosen model from a. Interpret all necessary statistics and conduct all necessary tests. c. State your estimated equation and interpret the coefficent of the first and last variable you have included. Use the estimated equation to predict the chance of admission for a Male student from Brazil with a CGPA of 8.5, a TOEFL of 110, a GRE of 320, no letter of recommendation, an interview score of 15 and who came from a mid rated (level 3) university which did not require a research project. (20 Marks) Summary Report 11. Write a brief report to GES describing what you have found in non-technical language. The report can be no longer than 200 words. Include your recommendations on the most important things to advise prospective international students.
