Peer-graded Assignment: Getting Your Research Project Started

Good afternoon, dear reader,

For my Data Visualization course assessment I have chosen working on the dataset provided by GapMinder organization.

After looking at the code book and variables available I decided that I am particularly interested in income rate dependences. Simple questions to answer include the following:

Is higher oil per person associated with higher income per person? If not, how it can be explained?

Is longer life expectancy associated with higher income per person?

How the rates of general/female employment connected to the income rate per person in  various countries?

For now I would like to concentrate more on the first question, but I suspect that there will be no linear correlation between oil and income per person. I checked the published articles and there was one that attracted my attention - Does oil drive income inequality? New panel evidence - ScienceDirect. It made me think to include policy score variable into my analysis as well, since average income cannot be a reliable variable if population inequality deepens. I'll need to create countries categorization based on policy score and it will be possible to additionally see the dependency between higher oil per person rate and worse policy scores.

As result, I'd like to determine if average income per person is dependent on oil per person rate taking policy score into consideration. Currently my assumption is that the average income grows with higher oil consumption, but the lower policy score is, the higher income inequality will be.

I prepared a partial code book for my further studies; it is attached below:
