Overview

This is the assignment task for the Developing Data Products course. I collected 20 car data from the Hungarian web side about selling used cars, page https://www.hasznaltauto.hu/. The collected data are the following:

  • Age (in months)
  • Mileage (in thousand kms)
  • Cylinder capacity (in thousand cm3, rounded up)

In the analysis I checked how the total mileage per age changed totally and also in various categories. I found that the higher the cylinder capacity is, the mileage per month increases.

The added cars are listed on the last slide (Appendix).

Results

Here are the results of the analysis:

  • Mileage per month of all cars: 809 km / month, meaning that an average car runs about 10.000 km in a year
  • Considering cylinder capacity: the higher the capacity is, it is most likely that the mileage per age increases
  • Mileage on cylinder capacity breakdown
    • Low category (at most 1.0): 409 km / month
    • Lower-mid category (between 1.0 and 2.0): 1012 km / month
    • Upper-mid category (between 2.0 and 3.0): 1399 km / month
    • Upper category (higher than 3.0): 1783 km / month
