BUS352 Tutor-Marked Assignment SINGAPORE UNIVERSITY OF SOCIAL SCIENCES (SUSS) Page 2 of 6 TUTOR-MARKED ASSIGNMENT (TMA) This assignment is worth 18% of the final mark for BUS352 Operations Analytics. The cut-off date for this assignment is 26 March 2023, 2355 hrs. Note to Students: You are to include the following particulars in your submission: Course Code, Title of the TMA, SUSS PI No., Your Name, and Submission Date. Important Note: Grading of TMA/GBA/ECA Submissions Marks awarded to your assignment are based on the following guidelines: 1. 80% of the marks are allocated to the content of your answers:  The marks awarded to what your answers cover depend on the extent to which they cover the key points that correctly and comprehensively address each question.  The key points should be supported by evidence drawn from course materials and, wherever relevant, from other credible sources. 2. 20% of the marks are allocated to the presentation of your answers: Wherever applicable, the marks awarded to how your answers are presented depend on the extent to which your answers:  form a sound reasoning by developing those key points in a clear, logical and succinct manner;  provide proper and adequate in-text citations and referencing to content drawn from course materials and other credible sources;  strictly follow APA formatting and style guidelines1, in particular for: • in-text citations and end-of-report references; • the identification of figures and tables;  use, wherever relevant, the specialised vocabulary and terminology commonly used in discussions about the topic(s) covered by each question;  provide a reference or bibliography at the end of the main report;  include the less relevant details in an Appendix;  use sentence constructions that are grammatically and syntactically correct; 1You can find a short tutorial on the APA formatting and style guidelines here: https://apastyle.apa.org/index.

BUS352 Tutor-Marked Assignment SINGAPORE UNIVERSITY OF SOCIAL SCIENCES (SUSS) Page 4 of 6 Instructions Students need to apply relevant theories, independent thinking, analytical judgment and problem-solving skills learnt in this course to address the questions. Students must demonstrate written proficiency by producing a type-written report in Microsoft Word 2013 or later (*.docx) format. Any key illustrations and diagrams should be shown in the main report with proper in-text citations. Students are required to embed their related Microsoft Excel worksheets (not screenshots, but the *.xlsx file) at the end of the Word document as an appendix for verification purpose. For those who do not know how to embed a file, please find the following link for helpful information: https://support.microsoft.com/en-us/office/insert-a-chart-from-an-excel-spreadsheet-into-word-0b4d40a5-3544-4dcd-b28f-ba82a9b9f1e1 Please note that:  The details and names used in the questions are fictional. Any resemblance to real-life situation is purely coincidental.  Students should not include the questions in the report.  An ability to (i) conduct proper research, provide the appropriate referencing of sources (students must provide proper in-text citations and an end-text reference list), and (ii) demonstrate critical thinking and creativity are all essential skills that our students must develop. Hence, marks will also be awarded for good research effort and proper referencing.  Fewer marks will be awarded to students who merely extract information from their reference sources without demonstration of critical analysis and creativity.  Answers that are simply reproduced from the course materials will be given very low marks or no marks. Question 1 Thanks to the outbreak of Covid-19, many educational institutes have transformed their course delivery from a face-to-face (F2F) mode to a virtual teaching mode. The operational processes in the F2F mode are different from those in the virtual teaching mode. For instance, instead of getting verbal feedback, instructors encouraged students to type in the Zoom chat tab to provide feedback. Dr. Goh is conducting online teaching for his students using Zoom. The course was delivered virtually over a six-week period, one lesson in each week. Dr. Goh encouraged students to participate in the Zoom session using chat tab. Dr. Goh would like to understand if the online participation can enhance students’ learning experience and their academic performance. Dr. Goh collected data to proceed with an analysis. He collected two variables, the total number of Zoom chat entries for each student over the six-week period, and the grades of students’ first assignment, which covers the topics in the first two weeks. For example, Student A001 has a total of 13 entries in the Zoom chat tab for the six weeks, and he/she receives 75 marks for his/her first assignment.
BUS352 Tutor-Marked Assignment SINGAPORE UNIVERSITY OF SOCIAL SCIENCES (SUSS) Page 5 of 6 (a) Analyse the chat entry number and academic performance data. Provide a visualisation and a numerical description of the two variables according to the following requirements: (i) Select one (1) appropriate chart type to visualise and present data. Provide a brief justification of your choice. What observations and conclusions can you make from the data visualisation? (Word Count: Maximum 250 words) (10 marks) (ii) Present descriptive statistics of the two variables. Provide a brief explanation of the key statistics. What can you observe and conclude from the descriptive statistics? Are these observations and conclusions consistent with those from (a)(i)? (Word Count: Maximum 200 words) (10 marks) (b) Dr. Goh hypothesises that chat participation strengthens students’ learning experiences and eventually enhances their academic performance. Dr. Goh wanted to find out if this hypothesis can be supported by the collected data. You are tasked to perform an association analysis according to the following requirements. (i) Use one (1) appropriate chart type to examine the relationship between the two variables. Provide a brief justification of your choice. What can you observe and conclude from the chart? (Word Count: Maximum 200 words) (12 marks) (iii) Use one (1) appropriate statistical tool to examine the relationship between the two variables. Clearly present the steps and components of the tool (if any), as well as the result of analysis. What can be concluded from the analysis? Is this conclusion consistent with the observations and conclusions in (b)(i)? (Word Count: Maximum 200 words) (13 marks) (c) In statistical analysis, the validity of the analysis can be adversely affected by skewness. Log transformation may help boost the validity by reducing or removing the skewness of the original data. Create a new variable by taking the natural logarithm of the chat entry data. For example, if the original data point is 13 entries, then the natural logarithm of this data point would be ln(13) = 2.56. You can use Excel function “LN()” to perform this transformation. Repeat (a)(i), (a)(ii), (b)(i) and b(ii) for this newly created variable and the grade data. Does this analysis yield any different conclusions or findings, compared to (a) and (b)? Please show the details of charting, descriptive statistics, calculation, analysis, and reasoning. (25 marks)
BUS352 Tutor-Marked Assignment SINGAPORE UNIVERSITY OF SOCIAL SCIENCES (SUSS) Page 6 of 6 (d) Every data analytics project has its limitations. What can be the limitations presented in this project and the improvements that Dr. Goh can make to enhance the validity, plausibility and robustness of the analysis and results? Provide a thorough discussion and clearly present your arguments. You may comment on the design of the data analytics project (e.g., data collection), hypothesis, rationale, tools, and methodologies used in the analytics, etc. (Word Count: Maximum 600 words) (30 marks) —- END OF ASSIGNMENT —-
