Q: What skills does a Data Scientist need?

Key skills for a Data Scientist include Core Skills, Programming (Python – primary; R, SQL – essential), Machine learning (supervised, unsupervised, evaluation metrics), Data wrangling and cleaning (Pandas, NumPy, SQL), Supporting Skills. These align strongly with Investigative personality types in the RIASEC framework.

A Data Scientist is an analytical professional who extracts insights, builds predictive models, and solves complex problems using data. They combine statistics, programming, machine learning, and domain expertise to turn raw data into actionable business value. This role exists across every industry: technology, finance, healthcare, retail, manufacturing, marketing, logistics, government, and research. Data Scientists help organizations make data-driven decisions, optimize operations, understand customers, predict trends, and automate processes. Often called the "sexiest job of the 21st century" (Harvard Business Review, 2012).

RIASEC Type: Investigative (I) Conventional (C), Enterprising (E)

What a Data Scientist does

Frame business problems as data science problems (what data is needed? what output?). Collect, clean, and preprocess data from multiple sources (SQL databases, APIs, logs). Explore and visualize data to identify patterns, anomalies, and relationships (EDA). Build statistical models (regression, classification, clustering, time series). Develop machine learning models (random forests, gradient boosting, neural networks)
