03 / FAQs
Questions before you start
What is the principle of data science?+
The core data science principles revolve around extracting meaningful insights from raw data using a structured approach. It includes data collection, cleaning, analysis, modeling, and visualization to solve real-world problems.
Is data science full of maths?+
Yes, but not overwhelmingly so. Data science relies on statistics, probability, and linear algebra, but modern tools (like Python libraries) handle complex calculations, letting you focus on applying concepts rather than deep math theory.
What are the 5 C's of data science?+
The 5 C’s framework covers:
- Capture (data collection)
- Clean (preprocessing)
- Curate (organizing data)
- Compute (analysis/modeling)
- Communicate (visualizing results)
What are the 7 V's of data science?+
The 7 V’s define big data challenges:
- Volume (size of data)
- Velocity (speed of data flow)
- Variety (different data types)
- Veracity (data accuracy)
- Value (extracting usefulness)
- Variability (inconsistencies)
- Visualization (presenting insights)
What is Python for data science?+
Python is the most popular programming language for data science, thanks to libraries like Pandas (data manipulation), NumPy (math operations), and Scikit-learn (machine learning). It simplifies complex tasks with readable, efficient code.
How to analyze big data?+
Data science for beginners starts with:
- Structured tools: Use Python/R + SQL.
- Cloud platforms: Leverage AWS, Google Cloud.
- Distributed computing: Try Apache Spark.
- Visualization: Power BI/Tableau for clarity.
What is the skill required by a data scientist?+
A data scientist should work to develop the following skillsets:
- Technical: Python/R, SQL, ML, statistics.
- Analytical: Critical thinking, problem-solving.
- Business Acumen: Translating data into decisions.
- Communication: Presenting insights clearly.
