You've mastered data science when you can:

Apply statistical concepts to real-world problems

Create informative data visualizations

Implement machine learning algorithms in Python

Communicate insights effectively to non-technical stakeholders

Not cleaning and preprocessing data properly

Leads to inaccurate insights and model performance

Instead: Use Pandas and NumPy to clean and preprocess data
