Overview
How to become a data analyst is one of the most searched career questions, partly because the role is open to people from many backgrounds. In England, the National Careers Service lists degree routes in subjects with strong statistics content, apprenticeships from Level 3 to Level 7, graduate schemes and government statistical roles. In the US there is no licence for the work, and the BLS does not publish a separate data analyst profile. This guide covers what analysts actually do, how the career grows and the practical steps in.
What a Data Analyst actually does
Data analysts turn raw data into answers people can act on. The job is often pictured as building dashboards; in practice a large share of time goes on finding the right data, cleaning it, and making sure the numbers mean what everyone thinks they mean. A typical request starts vague, such as "why did sales drop last month?", and the analyst's job is to sharpen the question, pull the data, check it, analyse it and explain the answer in plain language. You will write a lot of SQL, work in spreadsheets and BI tools, and spend real time on definitions: what counts as an active customer, which date to use, how to handle refunds. The best analysts are sceptical of their own results and clear when presenting them.
A typical week
- •Clarifying a request with a stakeholder so the question is specific enough to answer.
- •Writing SQL to pull data from several tables and checking the result against a known figure.
- •Cleaning data: fixing duplicates, missing values and inconsistent categories.
- •Building or updating a dashboard or report that a team uses to track performance.
- •Analysing a change in a metric and writing a short summary of what happened and why.
- •Presenting findings to a non-technical audience and answering follow-up questions.

The career path
Junior Data Analyst
Zero to around two yearsYou handle defined requests and recurring reports under guidance. The main growth is accuracy, SQL fluency and learning the business definitions.
Data Analyst
Roughly two to four yearsYou own analysis for an area of the business, shape questions with stakeholders and make recommendations, not only produce numbers.
Senior Data Analyst
Around four to seven yearsYou lead larger analyses, set standards for metrics and reporting, mentor others and influence decisions directly.
Lead Analyst / Analytics Manager
Seven years or moreYou manage a team or an analytics function, prioritise work across stakeholders and own the quality of the data the business relies on. Some analysts move into data science or data engineering instead.
The skills that matter
SQL
Most business data sits in databases. Writing correct, efficient queries is the skill analysts use most and are tested on most often.
Spreadsheets
Spreadsheets remain the common language of business. Lookups, pivot tables and clean structure are expected in almost every analyst role.
Statistics
Knowing when a change is meaningful and when it is noise prevents wrong conclusions. Basic statistics separates analysis from reporting.
Data visualisation and BI tools
A clear chart often communicates more than a table. Dashboards in BI tools are how many teams consume analysis.
Business understanding
Analysis is only useful if it answers the right question. Understanding how the business makes money helps you prioritise and interpret results.
Communication
Explaining findings simply, including their limits, is what turns analysis into decisions.
How to break in
- #1
UK (England): the National Careers Service lists degrees or postgraduate qualifications in statistics, maths, economics, operational research or psychology, or degrees with significant statistics content.
- #2
UK: apprenticeships listed include the Data Technician Level 3 Advanced Apprenticeship, the Data Analyst Level 4 Higher Apprenticeship and the Data Scientist Level 6 Degree Apprenticeship, plus a Software and Data Level 2 Foundation Apprenticeship for younger applicants.
- #3
UK: the National Careers Service also lists graduate schemes, the Civil Service Fast Stream's Government Statistical Service trainee places, and a college route such as the T Level in Digital Data Analytics leading to junior roles.
- #4
US: there is no licence for data analyst work. Build evidence instead: a portfolio of two or three analyses using public data, each with a clear question, clean SQL and a written conclusion.
- #5
If you are changing careers, start with data from your current field. A marketer, nurse or operations lead who analyses their own domain data has a strong story.
- #6
Practise timed SQL and spreadsheet tasks. Many analyst interviews include a practical exercise.
What drives pay
Compensation varies too much by country, sector and company size for a single figure to be useful. These are the factors that actually move it.
Technical depth, especially strong SQL, statistics and programming in Python or R.
Industry, since sectors value analysis differently.
How close your work is to major decisions or revenue.
Whether you shape questions and recommend actions, or mainly produce reports.
Location and whether the employer hires remotely.
Where demand is heading
Data analysis is used across almost every industry, and in England the National Careers Service lists employers from the NHS and government to retail and finance. BI tools and AI assistants now automate much routine reporting, so the value is shifting towards analysts who can frame good questions, check data quality and explain what results mean for a decision.
Roles this transfers to
Data Scientist
Strong analysts who add statistics, programming and modelling often move into data science.
Business Analyst
Understanding processes, gathering requirements and using data to support recommendations overlap heavily.
Data Engineer
Analysts who enjoy building reliable data pipelines and models can move into engineering the data itself.
Financial Analyst
Spreadsheet skill, careful analysis and clear reporting transfer well into finance teams.
Common mistakes
Collecting certificates without building analyses that show how you think.
Jumping into tools before learning SQL and basic statistics properly.
Presenting numbers without checking them against a known figure first.
Answering the question as asked instead of clarifying what the stakeholder actually needs.
Burying the conclusion under charts instead of leading with the answer.
Frequently Asked Questions
Do you need a degree to become a data analyst?
Not always. In England the National Careers Service lists apprenticeships from Level 3 upward and a college route alongside degrees. Many employers care most about practical skills you can demonstrate.
What skills do I need to become a data analyst?
SQL, spreadsheets, basic statistics, a visualisation or BI tool, and the ability to explain results clearly. Python or R helps for more advanced roles.
Can I become a data analyst with no experience?
Yes, through apprenticeships, graduate schemes or a portfolio. Using real public data to answer a clear question shows employers what you can do.
What is the difference between a data analyst and a data scientist?
Analysts mainly describe and explain what happened using data. Data scientists more often build statistical or machine learning models to predict or automate. The line varies between employers.
How can I practise data analyst tasks?
Work through realistic, timed tasks and get feedback. Cohesyve offers AI job simulations of data work with a scored report showing where you lost marks and a learning pathway. Three tests are free, with no card.
