Important things to know
Data analytics has become one of the most in-demand career paths in today’s digital economy. As organisations increasingly rely on data to guide decisions, the demand for skilled data analysts continues to grow across all industries. If you are looking to start a career in data analytics, understanding the technical skills and soft skills required is essential. This article explains the core skills needed to become a data analyst and how they work together to create impact.
What Does a Data Analyst Do?
A data analyst collects, cleans, analyses, and interprets data to help organisations make informed decisions. The role goes beyond working with numbers; it involves understanding business problems, extracting insights from data, and communicating findings clearly to stakeholders. To succeed, aspiring data analysts must develop both technical expertise and strong interpersonal skills.
Technical Skills Required for Data Analytics
Technical skills form the foundation of a data analytics career. These skills enable analysts to work with data efficiently and accurately.
1. Statistics and Analytical Foundations
Statistics is at the core of data analytics. A data analyst must understand how data behaves and how to draw valid conclusions from it. Foundational knowledge in descriptive statistics, probability, correlation, regression, and hypothesis testing helps analysts identify patterns, trends, and relationships in data. These skills ensure insights are statistically sound rather than based on assumptions.
2. Spreadsheet Skills (Excel or Google Sheets)
Spreadsheets remain one of the most widely used tools in data analytics, especially in entry-level roles. Proficiency in Excel or Google Sheets is essential for organising data, performing calculations, and conducting exploratory analysis. You should know how to use formulas, functions, pivot tables, and charts for data visualisation. Strong spreadsheet skills also help analysts quickly validate results before moving to more advanced tools.
Starting a career in data analytics is beyond the skills, employers reward work experience and an ability to show results from day one. That is why we built the data analytics work experience program
3. SQL for Database Management
SQL (Structured Query Language) is a critical skill for data analysts. For organisations that store data in relational databases, SQL allows analysts to retrieve, filter, aggregate, join large datasets, and write queries for analysis. A solid understanding of SQL significantly improves your ability to work with real-world data and is often a core requirement in data analyst job descriptions.
4. Data Visualisation and Business Intelligence Tools
Data visualisation helps transform complex datasets into clear insights. Data analysts use visualisation tools such as PowerBI and Tableau to create charts, reports and dashboards that highlight trends and support decision-making. Effective visualisation skills allow analysts to present insights in a way that is easy to understand and aligned with business goals.
5. Programming Languages (Python or R)
Programming skills enable data analysts to handle complex datasets and automate repetitive tasks. Python is the most popular programming language in data analytics due to its simplicity and extensive data libraries, while R is widely used for statistical analysis and research. Learning at least one programming language enhances analytical depth and career flexibility.
Soft Skills Required for a Career in Data Analytics
While technical skills help you analyse data, soft skills determine how effectively you apply those insights in real-world situations.
1. Analytical and Critical Thinking
Data analytics is fundamentally about problem-solving. Analytical thinking allows data analysts to ask the right questions, break down complex problems, and interpret results logically. Strong critical thinking helps analysts challenge assumptions and avoid misleading conclusions.
2. Communication and Storytelling Skills
One of the most important soft skills for data analysts is communication. Analysts must explain technical findings to non-technical audiences, write clear reports, and present insights in a compelling way. The ability to tell a clear data-driven story ensures that insights lead to informed decisions rather than confusion.
3. Business and Domain Understanding
Understanding the industry or business context behind the data is essential. Domain knowledge helps data analysts interpret results correctly and make relevant recommendations. Whether working in healthcare, finance, education, or marketing, context improves the quality and usefulness of insights.
4. Attention to Detail
Small errors in data can lead to incorrect conclusions. Attention to detail helps analysts spot inconsistencies, validate results, and ensure accuracy throughout the data analysis process. This skill is especially important during data cleaning and reporting stages.
5. Curiosity and Continuous Learning
Data analytics is a constantly evolving field. Successful data analysts are curious, adaptable, and committed to continuous learning. Staying updated with new tools, techniques, and industry trends helps analysts remain relevant and competitive.
How to Start Building Data Analytics Skills
A practical approach to starting a data analytics career involves learning foundational concepts, practising with real datasets, and building a portfolio. Focus first on statistics, spreadsheets, and business intelligence tools, then gradually expand into SQL, programming, and advanced analytics. By developing these skills progressively and applying them through practical projects, you can confidently begin and grow a successful career in data analytics.
