Common Mistakes Data Analysts Must Avoid โ ๏ธ๐
Even experienced analysts can fall into these traps. Avoid these mistakes to ensure accurate, impactful analysis!
1๏ธโฃ Ignoring Data Cleaning ๐งน
Messy data leads to misleading insights. Always check for missing values, duplicates, and inconsistencies before analysis.
2๏ธโฃ Relying Only on Averages ๐
Averages hide variability. Always check median, percentiles, and distributions for a complete picture.
3๏ธโฃ Confusing Correlation with Causation ๐
Just because two things move together doesnโt mean one causes the other. Validate assumptions before making decisions.
4๏ธโฃ Overcomplicating Visualizations ๐จ
Too many colors, labels, or complex charts confuse your audience. Keep it simple, clear, and focused on key takeaways.
5๏ธโฃ Not Understanding Business Context ๐ฏ
Data without context is meaningless. Always ask: "What problem are we solving?" before diving into numbers.
6๏ธโฃ Ignoring Outliers Without Investigation ๐
Outliers can signal errors or valuable insights. Always analyze why they exist before deciding to remove them.
7๏ธโฃ Using Small Sample Sizes โ ๏ธ
Drawing conclusions from too little data leads to unreliable insights. Ensure your sample size is statistically significant.
8๏ธโฃ Failing to Communicate Insights Clearly ๐ฃ๏ธ
Great analysis means nothing if stakeholders donโt understand it. Tell a story with dataโdonโt just dump numbers.
9๏ธโฃ Not Keeping Up with Industry Trends ๐
Data tools and techniques evolve fast. Keep learning SQL, Python, Power BI, Tableau, and machine learning basics.
Avoid these mistakes, and youโll stand out as a reliable data analyst!

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 clientโs 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, itโs availableโcollaboration is key!
End of the day:
1) Data analytics teams arenโt just about crunching numbersโtheyโre 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. Itโll 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!

SQL INTERVIEW Questions
Explain the concept of window functions in SQL. Provide examples to illustrate their usage.
Answer:
Window Functions:
Window functions perform calculations across a set of table rows related to the current row. Unlike aggregate functions, window functions do not group rows into a single output row; instead, they return a value for each row in the query result.
Types of Window Functions:
1. Aggregate Window Functions: Compute aggregate values like SUM, AVG, COUNT, etc.
2. Ranking Window Functions: Assign a rank to each row, such as RANK(), DENSE_RANK(), and ROW_NUMBER().
3. Analytic Window Functions: Perform calculations like LEAD(), LAG(), FIRST_VALUE(), and LAST_VALUE().
Syntax:
Examples:
1. Using ROW_NUMBER():
Assign a unique number to each row within a partition of the result set.
This query ranks employees within each department based on their salary in descending order.
2. Using AVG() with OVER():
Calculate the average salary within each department without collapsing the result set.
This query returns the average salary for each department along with each employee's salary.
3. Using LEAD():
Access the value of a subsequent row in the result set.
This query retrieves the salary of the next employee within the same department based on the current sorting order.
4. Using RANK():
Assign a rank to each row within the partition, with gaps in the ranking values if there are ties.
This query ranks employees within each department by their salary in descending order, leaving gaps for ties.
Tip: Window functions are powerful for performing calculations across a set of rows while retaining the individual rows. They are useful for running totals, moving averages, ranking, and accessing data from other rows within the same result set.

2. Ranking Window Functions: Assign a rank to each row, such as RANK(), DENSE_RANK(), and ROW_NUMBER().
3. Analytic Window Functions: Perform calculations like LEAD(), LAG(), FIRST_VALUE(), and LAST_VALUE().
Syntax:
SELECT column_name,
window_function() OVER (PARTITION BY column_name ORDER BY column_name)
FROM table_name;
Examples:
1. Using ROW_NUMBER():
Assign a unique number to each row within a partition of the result set.
SELECT employee_name, department_id, salary,
ROW_NUMBER() OVER (PARTITION BY department_id ORDER BY salary DESC) AS rank
FROM employees;
This query ranks employees within each department based on their salary in descending order.
2. Using AVG() with OVER():
Calculate the average salary within each department without collapsing the result set.
SELECT employee_name, department_id, salary,
AVG(salary) OVER (PARTITION BY department_id) AS avg_salary
FROM employees;
This query returns the average salary for each department along with each employee's salary.
3. Using LEAD():
Access the value of a subsequent row in the result set.
SELECT employee_name, department_id, salary,
LEAD(salary, 1) OVER (PARTITION BY department_id ORDER BY salary) AS next_salary
FROM employees;
This query retrieves the salary of the next employee within the same department based on the current sorting order.
4. Using RANK():
Assign a rank to each row within the partition, with gaps in the ranking values if there are ties.
SELECT employee_name, department_id, salary,
RANK() OVER (PARTITION BY department_id ORDER BY salary DESC) AS rank
FROM employees;

Most popular Python libraries for data visualization:
Matplotlib โ The most fundamental library for static charts. Best for basic visualizations like line, bar, and scatter plots. Highly customizable but requires more coding.
Seaborn โ Built on Matplotlib, it simplifies statistical data visualization with beautiful defaults. Ideal for correlation heatmaps, categorical plots, and distribution analysis.
Plotly โ Best for interactive visualizations with zooming, hovering, and real-time updates. Great for dashboards, web applications, and 3D plotting.
Bokeh โ Designed for interactive and web-based visualizations. Excellent for handling large datasets, streaming data, and integrating with Flask/Django.
Altair โ A declarative library that makes complex statistical plots easy with minimal code. Best for quick and clean data exploration.
For static charts, start with Matplotlib or Seaborn. If you need interactivity, use Plotly or Bokeh. For quick EDA, Altair is a great choice.
