If you’ve ever wondered how companies like Google, Netflix, or even local startups in Nigeria make data-driven decisions that skyrocket profits the answer lies in one role: the Data Analyst.
In 2025, data analysts are more valuable than ever. From marketing to finance, healthcare to government, everyone needs people who can turn numbers into insights. Let’s walk you through how to become a data analyst in 2025, even if you’re starting from scratch.
A data analyst collects, cleans, and interprets data to help companies make smarter decisions. Their day could involve analyzing customer behaviour, creating reports, or visualizing trends using tools like Power BI or Excel.
According to LinkedIn and Glassdoor, data analytics remains one of the top 10 fastest-growing careers globally. In Nigeria, more companies are investing in data teams to stay competitive — meaning skilled analysts are in high demand and well-paid.
1. Technical Skills:
Start with Microsoft Excel, it’s the foundation. Next, learn SQL for working with databases, Python for automation and analytics, and Power BI or Tableau for data visualization. These are the tools that employers love.
2. Analytical Thinking and Problem Solving:
It’s not just about knowing tools, it’s about solving problems. The best analysts ask questions like “What story is the data telling?” and “How can this insight improve business performance?”
3. Communication and Data Storytelling Skills:
A great analyst doesn’t just show charts, they tell stories with data. Learn how to explain complex findings in a simple, visual, and persuasive way.
Platforms like Coursera, Udemy, and ECR Academy provide structured, beginner-friendly courses. ECR Academy stands out for its practical, mentor-led sessions designed to help Nigerians learn real-world data skills fast.
A certificate is good, but what really gets you hired are projects that prove your skill. Focus on analyzing real data sets, visualizing insights, and building a personal portfolio.
Step-by-Step Guide to Starting Your Data Analyst Journey;
Step 1 : Learn the Basics of Data Analytics- Start by understanding data types, cleaning processes, and basic Excel analytics.
Step 2 : Master Essential Data Tools and Software- Pick one data visualization tool (like Power BI), one programming language (like Python), and SQL for querying databases.
Step 3 : Work on Real-Life Projects and Build a Portfolio- Analyze real datasets from Kaggle or Google. Build dashboards that show your work, these impress employers far more than certificates.
Step 4 : Network and Join Data Communities- Join Nigerian data communities like DataFest Africa or ECR Academy’s student community where you can collaborate and learn from others.
Step 5 : Apply for Internships or Entry-Level Data Jobs- Don’t wait to be perfect, start applying once you can clean, analyze, and present data confidently.
Power BI vs. Tableau – Which Should You Learn?
Both are powerful data visualization tools. Power BI is more popular in Nigeria due to its integration with Microsoft products and cost-effectiveness. Tableau, on the other hand, is preferred internationally for large-scale analytics and design flexibility. Learning one gives you a strong edge.
SQL is the backbone of data management. It allows analysts to retrieve, filter, and combine data from multiple sources efficiently. Without SQL, your analytical capabilities remain limited.
Python and R help automate data cleaning, handle large datasets, and even apply predictive models. For analysts aiming to grow into Data Science or Machine Learning, Python is a must-learn skill.
Top Industries Hiring Data Analysts
Data analysts are needed everywhere in finance, fintech, healthcare, oil & gas, retail, logistics, and e-commerce. Even small startups now rely on data to make informed decisions.
In 2025, Nigerian entry-level analysts earn between ₦250,000 and ₦500,000 monthly, while mid-level professionals earn ₦700,000 and above. Remote roles for foreign companies can pay $2,000–$5,000 monthly, making data analytics a financially rewarding path.
Once you gain experience in data analytics, you can move into more advanced roles such as Data Scientist, Machine Learning Engineer, or Business Intelligence Analyst. The possibilities are endless.

1.Focusing only on tools without understanding real business problems
2.Ignoring the importance of storytelling and presentation
3.Learning too many tools at once instead of mastering a few
4.Not building a portfolio of completed projects
