1. Project

2. Project Topic should be: Clear and specific
Practical and meaningful, this means the results of your research must have some implications in real life
Feasible to study (i.e. can be completed within the time limit you are given)

3. What is meant by a meaningful topic?
Some people may benefit from the research and it is possible to identify who they are
Topic that after conducting the test will lead to good conclusions and interpretations
Topic that is not obvious and the result of the test is not predictable
The inference process using sample to give conclusions about the population is meaningful

4. Project Choosing a topic
Should not copy from previous years (will receive a low mark if you do so)
Do not choose topics like: how many hours students spend per week using the library, or what students think about the ITM subject (or any other subject) (topics like these have been done many times by previous year students)

5. Where does the hypothesis come from?
Example: We want to test proportion of University A who have high-speed internet connection at home greater than >0.7
University plans to implement an online course that requires all of the students to have access to high-speed internet
University can support up to 30% of the students. So, more than 70% of the students would have to use their home computers.

6. Project Project questions
Hypothesis test (you carry out the necessary steps to test some hypothesis)
Descriptive statistics (you analyze the data to give some descriptive results)
So there is a main question answered using a hypothesis test, and there are some questions addressed in the descriptive part.

7. Project
The types of hypothesis tests that you will learn in this subject
Z test for 1 population mean
T test for 1 population mean
Z test for 1 population proportion

8. Project
The types of hypothesis tests that you will learn in this subject
Z test for comparing 2 population means (independent samples)
T test for comparing 2 population means (independent samples)
Z test for comparing two population proportions (independent samples)

9. Project
Think about the test you will apply, before choosing the topic (i.e. tests have assumptions; please check the lecture slides for the assumptions and guidelines of the tests)
Read the assumptions of the tests carefully
Project guidelines: available on the subject website; if you have any questions on project, please ask your tutor

10. Sampling
The way you select the sample will significantly affect the reliability of the project results (i.e. you should apply random sampling methods for your project if it is practical to do so).

11. Checking test assumptions
Some tests (e.g. the t-test) require that the population is normally distributed. If the sample size is large (n at least 30), it is possible to draw a histogram of the sample observations to check this assumption; if the histogram shows a bell-shaped distribution, then you can assume that the population is also (approximately) normal.

12. Checking test assumptions
If after collecting the sample data, you discover that some of the assumptions are not met, then you can try:
Choosing another type of test that requires fewer assumptions
Choosing a different population if applicable, or choosing a different topic (if time permits)

13. Checking test assumptions
If after some efforts, the assumptions are still not met, then you should proceed with other steps of the project. Remember to document the violation of the test assumptions in your report. The result of the test is no longer considered to be accurate, however students will still complete the project to understand the hypothesis testing process.

14. Project Report and Presentation
Read the project specification carefully (will be posted to faculty website)
Report: you are required to submit 1 hardcopy and 1 softcopy.
Presentation (using PowerPoint slides): some groups will present in lecture. For presentations in tutorials, the tutor will provide you with more information.

15. Project Presentation
Each group will appoint 4 students to speak. However, all group members have to be present and be prepared to answer questions.
The Q/A of presentation will be given 5 marks/20 (of the total project mark)
Teacher will give questions to both the presenters and non-presenters in the group. Teacher will choose who in the group answer which question. If the question is a difficult one, the teacher may allow the group to have a short discussion before answering.

16. Project Presentation
The presentation time is minutes but no more than 20 minutes.
Bonus marks for groups who can use R for data analysis (evidence must be demonstrated in the report and presentation to earn bonus marks)
