This Assignment consists of 2 Questions

QUESTION 1 [8 Marks]

With increasing congestion and the level of pollution in major cities, governments are trying to reduce the regular use of cars and encourage the use of public transport to travel to work. The following table presents data on the methods of travel used by Australian workers by age groups collected during on the census night for CENSUS 2016. The data are stored in file Assignment Dataset.XLS, TRAVEL sheet available in the Written Assignment folder. Using this data and EXCEL, answer the questions below.

QUESTION 2 [22 Marks]

A sociologist theorised that people who watch television frequently are exposed to many commercials, which in turn lead them to buy, resulting in increasing debt. These effects are believed to be vary by demographic and economic characteristics, such as age, gender and income of individuals. To test this belief, a researcher plans to survey a sample of families across the country.

Part 1 [3 marks]

Briefly explain

(a) What type of survey method could the researcher use and why?

(b) What sampling method could the researcher use to select his/her sample and why?

(c) What kind of issues the researcher may face in this data collection?

Suppose the researcher collected data from 400 randomly selected families. For each family, the total debt (in $) and the number of hours the television is turned-on per week (TV hours) were recorded. The data are stored in file Assignment Dataset.XLS TVDEBT sheet available in the Written Assignment folder. Using this data and EXCEL, answer the questions below.

Part 2 [8 Marks]

Firstly, the researcher wishes to use the graphical descriptive methods and numerical descriptive measures to present the data for the two variables.

(a) He/she decides to use 10 class intervals, such as 0 X=6, 6 X=12, 12 X=18, .... for the TV Hours variable and class intervals 0 X=30000, 30000 X=60000, 60000 X=90000, .... for the Total Debt variable. Explain how he/she could have decided on the number of classes as 10.

(b) Draw two histograms for the two variables using appropriate BIN values.

(c) Prepare a brief numerical summary report for the two variables; the total debt and the TV hours by including the summary measures, such as mean, median, variance, standard deviation, smallest and largest values, and the three quartiles, for each variable.

Notes: Use QUARTILE.EXC command to generate the three quartiles

(d) Based on your histograms in part (b) and descriptive summary measures in part (c), comment on the shape of the distribution of the two variables.

Cont.

Part 3 [6 Marks]

Secondly, the researcher wishes to investigate the association between the two variables.

(a) Explain what could be the independent variable (X) and the dependent variable (Y).

(b) Using Excel, compute a numerical measure that measures the direction and strength of the linear relationship between the total debt and TV hours. Interpret this value.

(c) Using an appropriate plot, investigate the relationship between total debt and TV hours.

(d) On the same plot in part (c), fit a linear trend line including the equation and the coefficient of determination (R2). Interpret the trend line equation coefficients and the coefficient of determination.

Part 4 [5 marks]

(a) Based on your findings above, write a brief research report on the relationship between total debt and TV hours (not more than 250 words).
