STA10003 FOUNDATIONS OF STATISTICS WORK INTEGRATED LEARNING ASSIGNMENT

The Industry Scenario

You are a new graduate researcher at the Victorian Department of Health. You have been given a dataset of members of the Australian Health and Social Science Panel. These members have completed an online Health Beliefs Survey. You have been tasked with conducting the initial analysis of some variables using SPSS, and to write brief reports.

Data Preparation

For Assignment Part 2 you can use the random sample of 1500 of the 2930 cases you generated from the original data file STA10003 Sem 1 2023 Assignment Data.sav. You do not need to generate a new random sample. If you have misplaced the random sample drawn for Assignment Part 1 you should draw a new random sample as per the instructions contained in the Assignment part 1 document. The data file STA10003 Sem 1 2023 Assignment Data.sav can be found on the Canvas page Week 10: Assignment Part 2 Instructions & Data File. This page can be accessed from Week 10: Assignment Part 2 page.

Submission Instructions

• Your submission must be a single Word file or PDF file.
• Although a cover page is not required, you should include your name and student number within the document [eg in footer].
• You must submit your file via Canvas by the specified due date and time. Only the last document you submit will be retained by Canvas.
• Once submitted, please review your submission to ensure the correct file has been submitted.
• This is an individual assignment. Do not share your work with other students. They will have a different random sample of data, so any copying will be detected.

ASSIGNMENT PART 2

For your Assignment Part 2, you are required to complete the first three questions by producing the appropriate analyses and writing the relevant report for each question. You are also required to complete question 4 containing short answer questions.

For each of the first three questions requiring SPSS, include the relevant output - tables and graphs. Provide all statistics to two decimal places, expect the p value which is given to three decimal places.

Question 1: Use of Complementary and Alternative Medicine Services

A psychologist at the Victorian Department of Health was investigating people’s use of complementary and alternative medicine services. Previous research indicated that Americans, on average, make use of 4.25 complementary and alternative medicine services. The psychologist predicted that there is a difference in the use of complementary and alternative medicine services between Australians and Americans. The variable Q9_CAM_services measures the number of complementary and alternative medicine services used. This variable was scored on a scale from 0 to 11, with higher scores indicating that a higher number of complementary and alternative medicine services were used. Conduct a one sample t-test using the Q9_CAM_services variable to test the psychologist’s claim. Produce the relevant output and write a one-sample t-test report based on your output in the style presented in Supplement G: Report Writing One Sample t-test & Binomial Test. Include the relevant output with your answer.

Question 2a: Spiritual Beliefs

A psychologist at the Victorian Department of Health was investigating people’s spiritual beliefs. The psychologist predicted that males have a higher level of spiritual beliefs than females. The variable Q5_SBC measures spiritual beliefs. This variable was scored on a scale from 1 to 4, with higher scores representing greater levels of spiritual beliefs. Conduct an independent samples ttest using the Q5_SBC and Q13 (Gender) variables to test the psychologist’s claim. Produce the relevant output and write an independent samples t-test report based on your output in the style presented in Supplement H: Reporting Independent samples t-tests. Include the relevant output with your answer.

Question 2b: Assumption Checking for the independent samples t-test

Check and comment on the assumptions of the independent samples t-test produced in Q2a. Include the relevant output with your answer.

Question 3a: Conspiracy and Paranormal Beliefs

A psychologist at the Victorian Department of Health was investigating people’s beliefs in conspiracies and in the paranormal. The psychologist believes that people have a higher belief in conspiracies than they have in the paranormal. The variable Q3_CBC measures people’s conspiracy beliefs. The variable Q4_PBC measures people’s paranormal beliefs. Both variables were scored on a scale from 1 to 4, with higher scores representing greater levels of beliefs.

Conduct a paired samples t-test using the Q3_CBC and Q4_PBC variables to test the psychologist’s claim. Produce the relevant output and write a paired samples t-test report based on your output in the style presented in Supplement J: Reporting Paired Samples t-test.

Question 3b: Assumption Checking for the paired samples t-test

Check and comment on the assumptions of the paired samples t-test produced in Q3a. Include the relevant output with your answer.

Question 4: Does not require SPSS

Post Easter a dietician wants to investigate chocolate consumption. The average per capita chocolate consumption in Europe is 5.0 kg. The dietician wanted to know if the amount of chocolate Australians consume differs to the amount of chocolate that Europeans consume. The dietician accessed a data set from the Australian Bureau of Statistics that contains information about food consumption for Australians who completed The Apparent Consumption of Foodstuffs survey.

1. What type of statistical test would be appropriate for the dietician to use?
2. What is the population we can draw conclusions about in this study?
3. The dietician predicted that, on average, the consumption of chocolate that Australians consume per capita differs to that consumed by Europeans. The dietician conducted the appropriate hypothesis test and obtained a p-value of 0.072. Based on this result the dietician concluded that there is no evidence to suggest that the amount of chocolate Australians consume is the same as the amount of chocolate that Europeans consume. Is this conclusion valid or not?
4. Comment on the validity of this conclusion. Provide justification for your answer. Prior to submitting your Assignment via Canvas, use the following checklist as a guide to ensure that all of the relevant information is provided.

Q1 – The One-sample t-test output including any additional output produced to answer the question. Report the results of the One-sample t-test following the format of reports in Supplement G: Report Writing One Sample t-test & Binomial Test.

Q2a – The Independent samples t-test output including any additional output produced to answer the question. Report the results of the Independent samples t-test following the format of reports in Supplement H: Reporting Independent samples t-test.

Q2b – The assumptions of the independent samples t-test produced in Q2a should all be addressed. Include the relevant SPSS output with your answer.

Q3a – The Paired samples t-test output and all other output produced to answer the question. Report the results of the Paired samples t-test following the format of reports in Supplement J: Reporting Paired samples t-test.

Q3b – The assumptions of the paired samples t-test produced in Q3a should all be addressed. Include the relevant SPSS output with your answer.

Q4– The answers should be presented with sections (a), (b), (c), and (d) clearly identified.
