Exercises 1.1

We are going to look at a Gapminder dataset, made famous by Hans Rosling from the Ted presentation ‘The best stats you’ve ever seen’.

    Read the dataset from the file data/gapminder.txt
    Find what are the oldest and youngest years in the dataset programatically
    Calculate average life expectancy as well as global population increase between these two years
    Find which country has the lowest life expectancy in 2002

Not clear: 'Find what are the oldest and youngest years in the dataset programatically'
Repharse it.
