(a) Data mining can be used to analyse the dataset and understand the public opinions of the quality of airline services, with an objective to improve customersâ air travel experiences.
Â
(i) Give one (1) example of descriptive data mining in this context and discuss how it can be used to achieve the stated objective. (15 marks)
(ii) Give one (1) example of predictive data mining in this context and discuss how it can be used to achieve the stated objective. (15 marks)
Â
(b) Suggest two (2) additional variables that can be included in formulating data analytics solutions for understanding customersâ air travel experiences. Explain the rationale of their inclusion. (30 marks)Â
Â
(c) Assume that there are two interesting findings obtained from the analysis:
⢠For economy class, most travellers who recommend the airlines give a rating of 4 or above to Value for Money.
⢠Leisure travellers have a lower mean rating of Inflight Entertainment than other types of travellers.
Give one (1) potential explanation of each finding. Then, propose one (1) solution for improving customersâ air travel experiences based on each finding. (20 marks)
Â
(d) Identify one (1) limitation of using the dataset stated in Table 1 to understand air travel experiences and propose one (1) way to address the limitation. (Note: The limitation should not be about the lack of variables you proposed in part (b).) (10 marks)
