World Values Survey: Singapore Data Analysis

Question 1 

 

For this question, you will need the file, “HBC203_TMA01_Q1.csv”. This file contains a subset of the Singapore data from the 2012 World Values Survey, after non-responses have been deleted. There are three variables in the file:
Sex, where 1 = male, 2 = female
Age
Happiness, where 1 = Very happy, 2 = Rather happy, 3 = Not very happy, 4 = Not at all happy

a. Import the file into jamovi. Then, where necessary, change the levels so that they are informative (e.g., under Sex, instead of “1”, we see “Male”). Change the measure type to match the scale of measurement of the variable. Take a screenshot of the jamovi spreadsheet (i.e., what you see when you click the DATA tab). Paste the screenshot in your answer. Make sure you capture the three variables in your screenshot. (6 marks)

b. Using jamovi, analyse the data to find the number of males and females who responded to the survey. Paste the relevant output from jamovi to support your answer.

c. Using jamovi, analyse the data to get the mean and the standard deviation of the Age variable. Paste the relevant output from jamovi to support your answer.

d. Show the distribution of the Age variable. Paste the relevant output from jamovi to support your answer. 

e. Use jamovi to calculate the percent of the total respondents who were at least rather happy (i.e., rather happy or very happy). Paste the relevant output from jamovi to support your answer

Question 2

a. Identify the predictor variable. State the number of conditions and identify what the conditions are. Identify the outcome variable. 

b. Identify the scale of measurement of the predictor variable and explain why. 

c. Identify the scale of measurement of the outcome variable and explain why.

d. Identify if this an experimental or observational study. Explain why in the context of this study.

e. Identify if this is a between-subjects or within-subjects design. Explain why in the context of this study to support your answer.

f. Based on the study design, identify the most appropriate parametric statistical test to conduct. Discuss why this is the most appropriate parametric test by providing two reasons in the context of this study. 

g. State the null hypothesis (H0) and the non-directional alternative hypothesis (H1). 

h. Enter the data into jamovi. Add informative labels to your variables. Change the measure type to match the scale of measurement of the variable. Show the jamovi spreadsheet by taking a screenshot of the spreadsheet (i.e., what you see when you click the DATA tab) and pasting it in your answer. Make sure you capture the variables in your screenshot.
