Assignment Description:
There are two datasets involved in this assignment: Dataset 1 and Dataset 2, detailed below.
Dataset 1: You will receive an email that contains a dataset that is specifically allocated to you. This dataset is edited from the original dataset provided by "Inside AirBNB" compiled on the 14 September 2019.

Your tasks are to provide a description for each dataset in Section 1, and to answer the following research questions given in Section 2 to Section 6 using dataset 1 or dataset 2 as indicated in each section.
Section 1: Description about Data:
a. Dataset 1: Give a short but clear description about this dataset. Is this primary or secondary data? What are the cases? How many variables are there in the dataset?
b. Dataset 2: Explain how you collect the data and discuss its limitation (e.g. whether your sample is biased). Is this primary or secondary data? What are the variables and their types?
Section 2: What are the proportions of different room types of AirBNB in Sydney?
Using Dataset 1, describe the proportion of the different room types available for rent in Sydney AirBNB. You need to provide the frequency and the proportion (either as a decimal or a percentage) as well as graphical display that easily shows the proportion of the room types.
Section 3: What is the AirBNB price distribution of private room after an iteration of outlier removal?
Using Dataset 1, perform one iteration of outlier detection on the price of private rooms using the method described in the lecture notes. After removing those outliers, describe the price distribution of private rooms using both numerical and graphical summary which shows the remaining outliers, if any.
Section 4: Is there a difference in the number of available days in the next 365 days among different room types?
Using Dataset 1, describe the distribution of availability for 365 days in the future, for each room type. You need to provide both numerical summary as well as graphical display which shows the outliers, if any.
Section 5: Is there any relationship between Longitude and Price?
Using Dataset 1, describe the relationship between the longitude of an AirBNB property location and its price. You need to provide both numerical summary as well as graphical display.
Section 6: Is there any relationship between gender and room type accommodation?
Using Dataset 2, describe the relationship between the gender of an international student and their current room type accommodation, e.g. whether the student currently shares a room, lives in a private room (but shares an apartment or a house) or lives in an apartment or a house by him/herself. You need to provide both numerical summary and graphical display.
