If you’re just starting out in Data Analytics, it’s super important to build the right habits early.
Here’s a simple plan for beginners to grow both technical and problem-solving skills together:
If You Just Started Learning Data Analytics, Focus on These 5 Baby Steps:
1. Don’t Just Watch Tutorials — Build Small Projects
After learning a new tool (like SQL or Excel), create mini-projects:
- Analyze your expenses
- Explore a free dataset (like Netflix movies, COVID data)
2. Ask Business-Like Questions Early
Whenever you see a dataset, practice asking:
- What problem could this data solve?
- Who would care about this insight?
3. Start a ‘Data Journal’
Every day, note down:
- What you learned
- One business question you could answer with data (Helps you build real-world thinking!)
4. Practice the Basics 100x
Get very comfortable with:
- SELECT, WHERE, GROUP BY (SQL)
- Pivot tables and charts (Excel)
- Basic cleaning (Power Query / Python pandas)
_Mastering basics > learning 50 fancy functions._
5. Learn to Communicate Early
Explain your mini-projects like this:
- What was the business goal?
- What did you find?
- What should someone do based on it?
React with ❤️ if you need a beginner-friendly roadmap to start your data analytics career

1. How many report formats are available in Excel?
There are three report formats available in Excel; they are:
1. Compact Form
2. Outline Form
3. Tabular Form
2. What are sets in Tableau?
Sets are custom fields that define a subset of data based on some conditions. A set can be based on a computed condition, for example, a set may contain customers with sales over a certain threshold. Computed sets update as your data changes. Alternatively, a set can be based on specific data point in your view.
3. What is the difference between DROP and TRUNCATE commands?
DROP command removes a table and it cannot be rolled back from the database whereas TRUNCATE command removes all the rows from the table.
4. What is slicing in Python?
Ans: Slicing is used to access parts of sequences like lists, tuples, and strings. The syntax of slicing is-[start:end:step]. The step can be omitted as well. When we write [start:end] this returns all the elements of the sequence from the start (inclusive) till the end-1 element. If the start or end element is negative i, it means the ith element from the end.
5. What is the map() and filter() function in Python?
The map() function is a higher-order function. This function accepts another function and a sequence of ‘iterables’ as parameters and provides output after applying the function to each iterable in the sequence. The filter() function is used to generate an output list of values that return true when the function is called.

How to Build an Impressive Data Analysis Portfolio
As a data analyst, your portfolio is your personal brand. It showcases not only your technical skills but also your ability to solve real-world problems.
Having a strong, well-rounded portfolio can set you apart from other candidates and help you land your next job or freelance project.
Here's how to build a portfolio that will impress potential employers or clients.
1. Start with a Strong Introduction:
Before jumping into your projects, introduce yourself with a brief summary. Include your background, areas of expertise (e.g., Python, R, SQL), and any special achievements or certifications. This is your chance to give context to your portfolio and show your personality.
Tip: Make your introduction engaging and concise. Add a professional photo and link to your LinkedIn or personal website.
2. Showcase Real-World Projects:
The most powerful way to showcase your skills is through real-world projects. If you don’t have work experience yet, create your own projects using publicly available datasets (e.g., Kaggle, UCI Machine Learning Repository). These projects should highlight the full data analysis process—from data collection and cleaning to analysis and visualization.
Examples of project ideas:
- Analyzing customer data to identify purchasing trends.
- Predicting stock market trends based on historical data.
- Analyzing social media sentiment around a brand or event.
3. Focus on Impactful Data Visualizations:
Data visualization is a key part of data analysis, and it’s crucial that your portfolio highlights your ability to tell stories with data. Use tools like Tableau, Power BI, or Python (matplotlib, Seaborn) to create compelling visualizations that make complex data easy to understand.
Tips for great visuals:
- Use color wisely to highlight key insights.
- Avoid clutter; focus on clarity.
- Create interactive dashboards that allow users to explore the data.
4. Explain Your Methodology:
Employers and clients will want to know how you approached each project. For each project in your portfolio, explain the methodology you used, including:
- The problem or question you aimed to solve.
- The data sources you used.
- The tools and techniques you applied (e.g., statistical tests, machine learning models).
- The insights or results you discovered.
Make sure to document this in a clear, step-by-step manner, ideally with code snippets or screenshots.
5. Include Code and Jupyter Notebooks:
If possible, include links to your code or Jupyter Notebooks so potential employers or clients can see your technical expertise firsthand. Platforms like GitHub or GitLab are perfect for hosting your code. Make sure your code is well-commented and easy to follow.
Tip: Organize your projects in a structured way on GitHub, using descriptive README files for each project.
6. Feature a Blog or Case Studies:
If you enjoy writing, consider adding a blog or case study section to your portfolio. Writing about the data analysis process and the insights you’ve uncovered helps demonstrate your ability to communicate complex ideas in a digestible way. It also allows you to reflect on your projects and show your thought leadership in the field.
Blog post ideas:
- A breakdown of a data analysis project you’ve completed.
- Tips for aspiring data analysts.
- Reviews of tools and technologies you use regularly.
7. Continuously Update Your Portfolio:
Your portfolio is a living document. As you gain more experience and complete new projects, regularly update it to keep it fresh and relevant. Always add new skills, projects, and certifications to reflect your growth as a data analyst.

Here's how I would learn Microsoft Excel for data analysis fast if I had to start from zero:
1) I would ignore most Excel courses/tutorials.
I'm going to be honest here.
Most Excel educational content does not teach you how to analyze data.
In most organizations, Excel is "business process glue."
This is what most courses teach.
2) I would start with Excel tables.
For analysis, you must have tables where:
Each row is an analytical item of interest (e.g., customers, patients, claims, etc.).
Each column is an attribute of these items.
Learn tables.
3) I would learn only PivotTable fundamentals.
For data analysis, tables of any kind are good for:
1. Looking up exact values.
2. Comparing exact values.
PivotTables are great, but most professionals overuse them.
Learn PivotTable fundamentals and then move on.
4) Learn data visualization.
Humans are visual creatures.
So learn:
Histograms
Line charts
Bar charts
Line charts
To visually analyze data.
This is way more powerful than only using PivotTables.
BTW - The best use for PivotTables is to feed PivotCharts!
5) Learn Power Query.
If you're serious about analyzing data with Excel, do yourself a favor and learn Power Query.
PQ skills allow you to clean and transform your data in powerful ways.
It also automates this as a repeatable process.
Use PQ instead of convoluted formulas.
6) Expand your skillset.
When you're ready, it's time to learn specific analysis techniques to up your game:
RFM analysis
Logistic regression
Market basket analysis
K-means cluster analysis
Decision tree machine learning
Some of these you can implement using Solver.
Others require...
7) Python in Excel
Microsoft is including Python in Excel as part of Microsoft 365 subscriptions.
That effectively makes it free for millions of professionals.
