📊 Data Science Essentials: What Every Data Enthusiast Should Know!
1️⃣ Understand Your Data
Always start with data exploration. Check for missing values, outliers, and overall distribution to avoid misleading insights.
2️⃣ Data Cleaning Matters
Noisy data leads to inaccurate predictions. Standardize formats, remove duplicates, and handle missing data effectively.
3️⃣ Use Denoscriptive & Inferential Statistics
Mean, median, mode, variance, standard deviation, correlation, hypothesis testing—these form the backbone of data interpretation.
4️⃣ Master Data Visualization
Bar charts, histograms, scatter plots, and heatmaps make insights more accessible and actionable.
5️⃣ Learn SQL for Efficient Data Extraction
Write optimized queries (
6️⃣ Build Strong Programming Skills
Python (Pandas, NumPy, Scikit-learn) and R are essential for data manipulation and analysis.
7️⃣ Understand Machine Learning Basics
Know key algorithms—linear regression, decision trees, random forests, and clustering—to develop predictive models.
8️⃣ Learn Dashboarding & Storytelling
Power BI and Tableau help convert raw data into actionable insights for stakeholders.
🔥 Pro Tip: Always cross-check your results with different techniques to ensure accuracy!

When starting off your data analytics journey you DON'T need to be a SQL guru from the get-go.
In fact, most SQL skills you will only learn on the job with:
- real business problems.
- actual data sets.
- imperfect data architecture.
- other people to collaborate with.
So be kind to yourself, give yourself time to grow and above all...
try to become proficient at SQL rather than perfect.
The rest will take care of itself along the way! 😉
