Data Science for Petroleum Engineering. Part 6 - Tidy data

One of the first concepts that one learns when working with data is rearranging raw data into tidy datasets. A tidy dataset not only means having the data in a row-column format but in such a way that a row corresponds to an observation and a column to a variable. This facilitates enormously the analysis. I know this could sound a little bit confusing, so I will show what raw data and tidy data looks like with an example.
