HBC203 Statistics and Data Analysis for the Social and Behavioural Sciences End-of-Course Assessment 2026, Singapore

HBC203 End-of-Course Assessment

This ECA carries 40% of the course marks and is a compulsory component. It is to be done individually and not collaboratively with other students. You must submit it on time.

Question 1

Overview 

In this assignment, you will apply the knowledge and skills that you learnt in HBC203 to a) develop research questions, b) analyse an existing data set using jamovi to answer those research questions, and c) interpret the results of your analyses.

To that end, you will submit a 2,000-word report. The word count includes tables but excludes the references and appendix sections. Words beyond the 2,000-word limit will NOT be graded. For example, the marker will read the first 2,000 words in a 2,300-word report and ignore the last 300 words. No penalty is imposed if you submit a report with less than 2,000 words.

Details about this assignment are described below.

Description of the study

Chronic sleep deprivation has been a growing concern in recent years due to its detrimental effects on multiple aspects of a person’s life. A group of sleep scientists would like to identify factors that are associated with chronic sleep deprivation so that they may offer solutions to alleviate this problem in Singapore. They sent out an email to all employees working in 7 major banks in Singapore to complete an online survey. All employees were highly encouraged to respond to the survey. They were given 1 month to complete the survey and received weekly email reminders to do so.

Dataset

The data collected from the study are presented in HBC203 ECA Dataset.csv. The table in the Appendix summarises the information gathered in the study and the response options for each question (if there were any).

Note for Mac users: Please use a web browser other than Safari to download the .csv file from Canvas. Otherwise, you may be unable to open the downloaded file.

Report

Structure your report in the following manner:

1. Introduction

(a) Briefly explain why it is important to address the growing concern on chronic sleep deprivation in Singapore.

(b) Identify FOUR research questions that you want to answer with this dataset.

• You must only use variables that are either already existing in the dataset or variables that you can create from the existing ones.
• You may change the scale of measurement of the variables (e.g., from continuous to categorical), if needed.
• You may use a subset of survey respondents in the dataset, where appropriate.
• If you choose to change the scale of measurement of the variables or use a subset of survey respondents, you must justify why you are doing so in your report.
• To show your ability to analyse different types of data, you must use at least TWO different analysis methods. In other words, you should not use the same analysis method (e.g., correlation) to answer all four research questions.
• You must only use analysis methods that have been taught in HBC203. No marks will be awarded for analysis methods that have not been taught in HBC203 regardless of whether it is a valid analysis method or not.

2. For EACH research question that you have identified:

(a) Write a short literature review to explain why it is important to investigate the research question.

• Use at least 2 academic references (e.g., journal articles, book chapters) per research question and cite all references in APA7 format.
• You may use references or research studies conducted in any country i.e., it does not have to be limited to Singapore.

(b) Clearly state what you expect to see in your analysis results (i.e., your prediction) and explain your prediction using findings from existing research.

(c) Conduct the analysis using Jamovi and report your results in the manner stated below:

• Identify the most appropriate analysis method to answer the research question and explain why that is the most appropriate analysis to use.
• Provide a screenshot of all Jamovi output that you used to interpret the results from your analysis. If you had created new variables from existing ones in the dataset, clearly describe how these new variables were created and provide a screenshot of the Jamovi dataset with the new variables.
• Ensure that your screenshots are clear and easy to read at Word document Zoom setting of 100%. No marks will be awarded if the marker is unable to clearly and easily read the details (e.g., numbers) in your screenshots.
• Interpret the Jamovi output fully and report your results in APA format.

(d) Discuss the results from your analysis. Your discussion should minimally address these questions below:

• Do the results from your analysis support your prediction?
• How similar or different are your results from what is presented in the literature? Why might there be differences?
• What are the practical or theoretical implications of your results? That is, how can we use what you have found in your analysis?
• What are the key limitations in this study that could reduce the credibility of the results?
• How would you address the limitations (e.g., what other information would you collect if you were to conduct this study)?
• Justify what you would do to address the limitations (e.g., why would collecting additional information address the limitations).

3. Conclusion

Provide a summary of key findings and implications based on the analyses from the four research questions.

4. Word count

• State the number of words written from the Introduction section to Conclusion section (including all headings, citations, and tables).
• Exclude the jamovi output from your word count.

5. References

• Provide a list of all references that you cited in your report.
• Your report must adhere to APA standards of formatting and reference. It should also be clear, concise, and coherent. Refer to this website for the latest APA style guide (7th edition): https://apastyle.apa.org/style-grammar-guidelines.
