Your first steps towards becoming a top performer
Your first step towards becoming a top-performing data scientist is mastering the foundations:

  • data visualization
  • data manipulation
  • exploratory data analysis

Have you mastered these? Have you memorized the syntax to accomplish these? Are you “fluent” in the foundations?

If not, you need to go back and practice. Believe me. You’ll thank me later. (You’re welcome.)

The reason is that these skills are used in almost every part of the data science workflow, particularly in earlier parts of your career.

Given almost data task, you’ll almost certainly need to clean your data, visualize it, and do some exploratory data analysis.

Moreover, they are also important as you move into more advanced topics. Do you want to start doing machine learning, artificial intelligence, and deep learning? You had better know how to clean and explore a dataset. If you can’t, you’ll basically be lost.
