2BUS708 STATISTICS AND DATA ANALYSISSection 1: Introduction1.1 IntroductionLodging a tax return at the end of each financial year is important for a lot of people in Australia.The people of Australia can do this by preparing and lodging their tax returns by themselves or get itdone by paying any registered tax agent. According to Kennedy et al. (2017), most of the people ofAustralia prefer to get their lodgements done with the help of tax agents. This is a very vital work andpreparing their own tax returns might cause some errors which will be a problem for the individual inthe later years. So unless they are an expert in this matter, people prefer to get it done by agents. Thisstudy mainly aims to find out the proportion of people who are lodging their tax returns by themselvesand with the help of agents. The relationships between total income, lodgement method and deductionamount are also to be assessed. The preference of the international students on the lodgementmethods of tax return are also to be assessed. 1.2 Explanation of the Tax Return DatasetThe first dataset has been collected from the Australian Taxation Office (ATO). This is a subset of1000 people of the 2013-2014 dataset available on their website. The variables that are involved in thedataset are Gender, Age Range, Lodgement Method, Total income and total deduction. Here, thevariables Gender, Age Range and Lodgement Method are categorical variables and the variables totalincome and total deductions are continuous variables. The data is secondary as it is collected from theATO website. The first five cases of the dataset are attached in table 1.1.Table 1.1: First five cases of Tax Return Dataset1.3 Explanation of the International Students DatasetData on the preference of international students were collected with the help of a survey. Asample of 100 students were asked about their preferences of their tax return lodgement method. Thisis a primary data as it has been collected directly from the students for the purpose of the study andwere not pre-recorded. This is a categorical variable. Section 2: Lodgement Method – Dataset 1For dataset 1, it can be seen that out of 1000 people, 738 people prefer lodging their tax returnswith the help of registered tax agents. Thus, it can be said that most of the people of Australia preferlodging tax returns with the help of agents.

Section 3: Lodgement Method – Dataset 2From the sample of 100 international students collected, it can be seen that 74 of them preferto lodge tax returns using agents.
