Recently a small data set was posted on a discussion board I read. 5 columns by 15 rows. This small bit of data yielded an immense number of opinions and visualizations.
If you aspire to be a data scientist, you’re really aspiring to be a data wrangler. You see, 80% of your working hours will be spent wrangling the data. That’s on average. On some projects, you will spend more than 100% of your “working” hours with your lasso. I hope you enjoy that sort of thing.
