Best Practices for Using Power Query Editor :
To make the most out of Power Query Editor, follow these best practices:
1. Remove Unnecessary Columns
Keep only the columns you need to reduce file size and improve performance.
2. Apply Filters at the Earliest Stage
Filtering early reduces the data load, making queries run faster.
3. Use Merge Queries Instead of VLOOKUP
If you need data from another table, use Merge Queries instead of writing complex DAX formulas.
4. Keep Applied Steps Organized
Rename steps for better readability and avoid unnecessary transformations.
5. Enable Query Folding for Performance Optimization
Query Folding allows Power Query to push transformations to the data source, improving performance.

What is a Histogram in Power BI?
- A histogram is a powerful visualization tool in Power BI that helps analyze data distribution by grouping values into defined intervals or bins. Unlike a bar chart, which compares categories, a histogram focuses on how frequently data points fall within specific numeric ranges.
- A histogram is a type of bar chart that visualizes the frequency distribution of numerical data by grouping values into bins (ranges). It helps businesses analyze trends, detect outliers, and make informed decisions.

Can AI Completely Replace Data Analysts?
Despite AI’s capabilities, it has limitations:
1. AI Lacks Business Context & Critical Thinking
- AI cannot understand business goals, market trends, or human emotions.
- AI suggests patterns, but it cannot determine strategic actions based on insights.
Example: AI can identify a sales drop, but only a human analyst can explain why it happened.
2. AI is Only as Good as the Data It Learns From
- AI depends on quality data—poor data leads to inaccurate results.
- AI models cannot detect bias in datasets without human supervision.
Example: If an AI-driven hiring model is trained on biased data, it will continue biased hiring decisions unless humans correct it.
3. AI Cannot Replace Human Creativity & Soft Skills
- AI lacks creativity, problem-solving, and negotiation skills.
- AI cannot collaborate, lead teams, or interpret business goals.
Example: In a business meeting, a data analyst explains insights to leadership, whereas AI just provides numbers.

Why Does Power BI Hide Items with No Data?
By default, Power BI removes empty values from visuals due to:
Performance Optimization – Displaying only relevant data speeds up processing.
Visual Clarity – Avoids clutter in charts and tables.
Implicit Filtering – Power BI automatically excludes categories that don’t have matching records.
