A simple beginner’s guide to data analysis
Across the UK, one tech skill keeps appearing in job listings again and again: data analysis.
From retail and healthcare to finance and marketing, companies are looking for people who can understand data and turn it into useful insights.
The best part? You don’t need a computer science degree to get started.
This guide breaks it down step by step in plain English so you can begin from scratch.
What is data analysis?
Data analysis means looking at information and finding patterns, trends or answers.
For example:
- A business might analyse sales to see what products are popular
- A hospital might analyse patient data to improve care
- A website owner might track visitor behaviour
In simple terms, it’s about turning numbers into decisions.
Why is it in high demand in the UK?
UK businesses are collecting more data than ever before.
But data alone is useless unless someone can interpret it.
That’s where data analysts come in.
Entry-level roles are growing fast, and salaries are often higher than average for junior positions. Many roles also offer remote or flexible working.
For people looking for a career change or a side hustle, this makes data analysis a strong option.
The key skills you need (don’t worry – they’re learnable)
Before diving in, here are the main skills you’ll build:
- Basic maths (nothing advanced)
- Spreadsheets (like Excel or Google Sheets)
- Data visualisation (charts and graphs)
- Beginner coding (usually Python or SQL)
- Problem solving and thinking logically
You don’t need to master everything at once.
Step by step: How to get started
Step 1: Learn the basics of spreadsheets
Start with Excel or Google Sheets.
These tools are the foundation of data analysis and are used in almost every job.
Focus on:
- Sorting and filtering data
- Simple formulas (SUM, AVERAGE)
- Creating charts
You can learn this in a few days with free tutorials.
Step 2: Understand what data actually looks like
Next, get comfortable working with real datasets.
You can find free datasets online (for example, sales data or survey results).
Practice:
- Looking for patterns
- Asking simple questions (What’s increasing? What’s decreasing?)
- Cleaning messy data
This step helps you think like an analyst.
Step 3: Learn basic data visualisation
Data is easier to understand when it’s visual.
Learn how to turn numbers into charts, such as:
- Bar charts
- Line graphs
- Pie charts
Tools like Excel or free platforms like Tableau Public are great for beginners.
Step 4: Start learning SQL (a beginner-friendly coding language)
SQL is used to access and organise data stored in databases.
It might sound technical, but it’s actually one of the easiest coding languages to learn.
You’ll use it to:
- Retrieve data
- Filter results
- Combine information from different tables
Many free websites offer interactive SQL practice.
Step 5: Learn basic Python (optional but powerful)
Python is a popular programming language used in data analysis.
You don’t need to become an expert.
Start with:
- Reading data
- Simple calculations
- Basic visualisations
This step can come later, once you feel confident with spreadsheets and SQL.
Step 6: Build small projects
This is where everything starts to click.
Create simple projects, such as:
- Analysing supermarket prices
- Tracking your personal spending
- Looking at football statistics
Projects help you apply what you’ve learned and are useful for job applications.
Step 7: Create a simple portfolio
A portfolio shows employers what you can do.
It doesn’t need to be complicated.
Include:
- 2-3 small projects
- Clear explanations of your findings
- Charts or visuals
You can share this online using free platforms.
Step 8: Apply for entry level roles or freelance work
Once you have basic skills and a portfolio, start applying.
Look for roles like:
- Junior data analyst
- Reporting assistant
- Business analyst (entry level)
You can also find freelance work or short term projects online.
How long does it take to learn?
Most beginners can learn the basics in 3 to 6 months with consistent effort.
If you study part-time (a few hours a week), it may take longer but it’s still achievable.
The key is consistency, not speed.
How much can you earn in the UK?
Entry-level data analysts in the UK often earn between:
- £25,000 to £35,000 per year
With experience, this can rise to:
- £40,000 to £60,000+
Freelancers can charge per project or hourly, depending on their skills.
Common mistakes beginners make
Trying to learn everything at once
Stick to one tool at a time. Start with spreadsheets.
Skipping practice
Watching tutorials is not enough. You need hands-on work.
Overthinking coding
You don’t need advanced programming skills to start.
Not building projects
Projects are what employers care about most.
Why this skill could change your career
Data analysis is flexible.
It can lead to roles in:
- Marketing
- Finance
- Tech
- Healthcare
- Sports
It also works well as a side hustle or freelance skill.
In a job market where stability can feel uncertain, having a practical, in demand skill can make a big difference.
