This project is a data mining project which required us using complex dataset to find out meaningful or interesting insights. In this project, I analyzed main factors which may influence people’s life expectancies in G20 countries. Main factors that I used are blood pressure, body mass index, cholesterol, GDP per capita, healthcare expenditure and gender. I have already uploaded all of files and dataset that I used during the project. If you are interested in my findings, please download the entire folder.
