What to Expect
Data science evaluation combines statistical rigor with practical analysis skills. You'll review AI-generated analytical approaches and assess whether they're statistically valid—does this regression account for multicollinearity? Is this A/B test properly powered? Does this correlation claim establish causation? Tasks often provide a dataset scenario and ask you to evaluate whether the AI's chosen method (e.g., logistic regression vs. random forest) is appropriate and whether conclusions drawn from the analysis are defensible. SQL query evaluation is common: you'll check for correctness, performance, and whether window functions are used appropriately. Proficiency in Python (pandas, scikit-learn, statsmodels) and SQL is expected.

Frequently Asked Questions
What data science skills are required?
Strong foundation in statistics, Python (pandas, numpy, scikit-learn), SQL, and data visualization. Experience with A/B testing, regression analysis, and feature engineering is valuable.
Is a Master's degree required?
Not always. Bachelor's + 3+ years professional data science experience qualifies for many roles. Master's or PhD in statistics, data science, or related field unlocks higher-paying opportunities ($80-110/hr).
What's the difference from ML engineering roles?
Data science roles focus on statistical analysis, business insights, and data exploration. ML engineering focuses on model training and deployment. Some overlap exists, but data science emphasizes analysis over engineering.
How much can data scientists earn?
Entry-level data scientists: $50-70/hr. Senior data scientists: $70-90/hr. PhD statisticians: $90-110/hr. Kaggle competition winners and specialized experts may earn more.
