Define a Question and Getting Your Data Science Project Started

A typical data science project will be structured in mainly five different phases.

Structure of a Data Science Project | Different Phases in Data Science Project

The first phase is always the most important phase, and that’s the phase where you ask the question and you specify what is it that you’re interested in learning from data.I would like to examine the Gapminder Dataset and  how gross domestic product (GDP) is related to urbanization? As income per person may depend on urbanization and employment rate. Alternatively GDP may lost when unemployment rate is high. So, basically here I would like to explore the relationship between income per person and two other variables:

1.      Urbanization

2.      Employment Rate

Data Science Questions:

1.      Is GDP associated Urbanization(Urban Rate)?

2.      Is GDP has any relationship with employment rate? Is a bigger GDP implies a higher employment rate?

My hypothesis is a positive answer to this two questions.


My variable of interest are:

There are so many variables in the data set but I am interested only in three variables given below.


My hypothesis is a positive answer to the above two questions. I think it may be feasible to hypothesize that both “employrate” and “urbanrate” variables are positively associated with “incomeperperson”.
