ENJOY LEARNING 👍👍

I’m a data analyst.

I clean and prepare data daily for my job.

This is how I would learn data cleaning for 2025:
✅Learn how to handle missing values
✅Learn data normalization and standardization
✅Learn to remove duplicates
✅Learn how to handle outliers
✅Learn how to merge and join datasets
✅Learn to identify and correct data inconsistencies

Data cleaning is an essential step to make your analysis meaningful.

Skills a data analyst needs:

1. Technical skills
📍 SQL
📍 Excel
📍 Data viz (Power BI/Tableau)

2. Soft skills
📍 Problem solving
📍 Communication
📍 Thinking (critical + analytical)
