If I need to teach someone data analytics from the basics, here is my strategy:

1. I will first remove the fear of tools from that person

2. i will start with the excel because it looks familiar and easy to use

3. I put more emphasis on projects like at least 5 to 6 with the excel. because in industry you learn by doing things

4. I will release the person from the tutorial hell and move into a more action oriented person

5. Then I move to the sql because every job wants it , even with the ai tools you need strong understanding for it if you are going to use it daily

6. After strong understanding, I will push the person to solve 100 to 150 Sql problems from basic to advance

7. It helps the person to develop the analytical thinking

8. Then I push the person to solve 3 case studies as it helps how we pull the data in the real life

9. Then I move the person to power bi to do again 5 projects by using either sql or excel files

10. Now the fear is removed.

11. Now I push the person to solve unguided challenges and present them by video recording as it increases the problem solving, communication and data story telling skills

12. Further it helps you to clear case study round given by most of the companies

13. Now i help the person how to present them in resume and also how these tools are used in real world.

14. You know the interesting fact, all of above is present free in youtube and I also mentor the people through existing youtube videos.

This is how data analytics teams work!

Example:
1) Senior Management at Swiggy/Infosys/HDFC/XYZ company needs data-driven insights to solve a critical business challenge.

So, they onboard a data analytics team to provide support.

2) A team from Analytics Team/Consulting Firm/Internal Data Science Division is onboarded.
The team typically consists of a Lead Analyst/Manager and 2-3 Data Analysts/Junior Analysts.

3) This data analytics team (1 manager + 2-3 analysts) is part of a bigger ecosystem that they can rely upon:
- A Senior Data Scientist/Analytics Lead who has industry knowledge and experience solving similar problems.
- Subject Matter Experts (SMEs) from various domains like AI, Machine Learning, or industry-specific fields (e.g., Marketing, Supply Chain, Finance).
- Business Intelligence (BI) Experts and Data Engineers who ensure that the data is well-structured and easy to interpret.
- External Tools & Platforms (e.g., Power BI, Tableau, Google Analytics) that can be leveraged for advanced analytics.
- Data Experts who specialize in various data sources, research, and methods to get the right information.

4) Every member of this ecosystem collaborates to create value for the client:
- The entire team works toward solving the client’s business problem using data-driven insights.
- The Manager & Analysts may not be industry experts but have access to the right tools and people to bring the expertise required.
- If help is needed from a Data Scientist sitting in New York or a Cloud Engineer in Singapore, it’s available—collaboration is key!

End of the day:
1) Data analytics teams aren’t just about crunching numbers—they’re about solving problems using data-driven insights.
2) EVERYONE in this ecosystem plays a vital role and is rewarded well because the value they create helps the business make informed decisions!
3) You should consider working in this field for a few years, at least. It’ll teach you how to break down complex business problems and solve them with data. And trust me, data-driven decision-making is one of the most powerful skills to have today!

5 misconceptions about data analytics (and what's actually true):

❌ The more sophisticated the tool, the better the analyst
✅ Many analysts do their jobs with "basic" tools like Excel

❌ You're just there to crunch the numbers
✅ You need to be able to tell a story with the data

❌ You need super advanced math skills
✅ Understanding basic math and statistics is a good place to start

❌ Data is always clean and accurate
✅ Data is never clean and 100% accurate (without lots of prep work)

❌ You'll work in isolation and not talk to anyone
✅ Communication with your team and your stakeholders is essential

Essential Excel Concepts for Beginners

1. VLOOKUP: VLOOKUP is a popular Excel function used to search for a value in the first column of a table and return a corresponding value in the same row from another column. It is commonly used for data lookup and retrieval tasks.

2. Pivot Tables: Pivot tables are powerful tools in Excel for summarizing and analyzing large datasets. They allow you to reorganize and summarize data, perform calculations, and create interactive reports with ease.

3. Conditional Formatting: Conditional formatting allows you to format cells based on specific conditions or criteria. It helps highlight important information, identify trends, and make data more visually appealing and easier to interpret.

4. INDEX-MATCH: INDEX-MATCH is an alternative to VLOOKUP that combines the INDEX and MATCH functions to perform more flexible and powerful lookups in Excel. It is often preferred over VLOOKUP for its versatility and robustness.

5. Data Validation: Data validation is a feature in Excel that allows you to control what type of data can be entered into a cell. You can set rules, create drop-down lists, and provide error messages to ensure data accuracy and consistency.

6. SUMIF: SUMIF is a function in Excel that allows you to sum values in a range based on a specific condition or criteria. It is useful for calculating totals based on certain criteria without the need for complex formulas.

7. CONCATENATE: CONCATENATE is a function in Excel used to combine multiple text strings into one. It is helpful for creating custom labels, joining data from different cells, and formatting text in a desired way.

8. Goal Seek: Goal Seek is a built-in tool in Excel that allows you to find the input value needed to achieve a desired result in a formula. It is useful for performing reverse calculations and solving what-if scenarios.

9. Data Tables: Data tables in Excel allow you to perform sensitivity analysis by calculating multiple results based on different input values. They help you analyze how changing variables impact the final outcome of a formula.

10. Sparklines: Sparklines are small, simple charts that provide visual representations of data trends within a single cell. They are useful for quickly visualizing patterns and trends in data without the need for larger charts or graphs.
