If you鈥檙e getting ready to launch a new career as a data analyst, chances are you鈥檝e encountered an age-old dilemma. Job listings often require experience, but how do you get said experience if you鈥檙e seeking your first data analyst job? This is where your portfolio comes in.

The projects you include in your portfolio demonstrate your skills and experience鈥攅ven if it鈥檚 not from a previous data analytics job鈥攖o hiring managers and interviewers. Populating your portfolio with the right projects can go a long way toward communicating that you鈥檙e the right person for the job, even without previous work experience.

Explore five essential data analytics portfolio projects, particularly if you鈥檙e new to the field.聽 See some examples of how people present these projects in real portfolios, and find a list of public data sets you can use to start completing projects.

Tip: When you鈥檙e just starting out, think in terms of 鈥渕ini projects.鈥� A portfolio project doesn鈥檛 need to feature a complete analysis end-to-end. Instead, complete smaller projects based on individual data analytics skills or steps in the data analysis process.

Data analysis project ideas

As an aspiring data analyst, you鈥檒l want to demonstrate a few key skills in your portfolio. These data analytics project ideas reflect the tasks often fundamental to many data analyst roles.聽

1. Web scraping

While you鈥檒l find no shortage of excellent (and free) public data sets on the internet, you might want to show prospective employers that you鈥檙e able to find and scrape your own data as well. Plus, knowing how to scrape web data means you can find and use data sets that match your interests, regardless of whether or not they鈥檝e already been compiled.

If you know some Python, you can use tools like Beautiful Soup or Scrapy to crawl the web for interesting data. If you don鈥檛 know how to code, don鈥檛 worry. You鈥檒l also find several tools that automate the process (many offer a free trial), like Octoparse or ParseHub.

If you鈥檙e unsure where to start, below are some websites with interesting data options to inspire your project:

• Reddit

• Wikipedia

• Job portals

Tip: Anytime you鈥檙e scraping data from the internet, remember to respect and abide by each website鈥檚 terms of service. Limit your scraping activities so as not to overwhelm a company鈥檚 servers, and always cite your sources when you present your data findings in your portfolio.

Example web scraping project: Hosting and cloud partner IONOS provides to search through the available online listings of used cars鈥攕pecifically the Volkswagen Beetle.聽

2. Data cleaning

A significant part of your role as a data analyst is cleaning data to make it ready for analysing. Data cleaning (also called data scrubbing) is the process of removing incorrect and duplicate data, managing any holes in the data, and ensuring consistent data formatting.聽聽

As you look for a data set to practise cleaning, look for one that includes multiple files gathered from multiple sources without much curation. Some sites where you can find 鈥渄irty鈥� data sets to work with include:

• London Air

• Data.gov.uk

• World Bank

• Data.world

• /r/datasets

Example data cleaning project: Consider this series of straightforward data cleaning projects, as outlined by . They explore different data types and formats, and methods to clean and reorganise data for analysis and visualisation.

3. Exploratory data analysis (EDA)

Data analysis is all about answering questions with data. Exploratory data analysis, or EDA for short, helps you explore what questions to ask. This could be done in conjunction with, or in conjunction with, data cleaning. Either way, you鈥檒l want to accomplish the following during these early investigations.

1. Ask lots of questions about the data.

2. Discover the underlying structure of the data.

3. Look for trends, patterns, and anomalies in the data.

4. Test hypotheses and validate assumptions about the data.

5. Think about what problems you could potentially solve with the data.

Example exploratory data analysis project: , along with information on supply vulnerability, online exposure, a clone town measure (which assesses retail centre diversity), E-resilience, and hierarchical classification.聽

9. : This Metropolitan Police Services dataset is updated monthly at the beginning of every month.

10. : See what you can find while exploring this collection of Yelp user reviews, check-ins, and business attributes.

4. Sentiment analysis

Sentiment analysis, typically performed on textual data, is a technique in natural language processing (NLP) for determining whether data is neutral, positive, or negative. It may also be used to detect a particular emotion based on a list of words and their corresponding emotions (known as a lexicon).聽

This type of analysis works well with public review sites and social media platforms, where people are likely to offer public opinions on various subjects.

To start exploring people鈥檚 opinions on a certain topic, consider beginning with sites like:

• Amazon (product reviews)

• Rotten Tomatoes (movie reviews)

• Facebook

• Twitter/X

• UK news sites

Example sentiment analysis project: This study via ResearchGate, entitled , uses sentiment analysis.聽 The main aim is to understand depression levels in users and correlate the scores to the main data.聽

5. Data visualisation

Humans are visual creatures. This makes data visualisation a powerful tool for transforming data into a compelling story to encourage action. Great visualisations are not only fun to create, but they also have the power to make your portfolio look beautiful.

Example data visualisation project: outlines the 10 Of The Best Data Visualization Examples From History & Today, including The Napoleon March Map, to Disney Film Dialogue (broken down by gender).聽

Five free data visualisation tools

You don鈥檛 need to pay for advanced visualisation software to start creating stellar visuals either. These are just a few of the free visualisation tools you can use to start telling a story with data:

1. Tableau Public: Tableau ranks among the most popular visualisation tools. Use the free version to transform spreadsheets or files into interactive visualisations ( celebrating the 2024 Vizzie Award Winners).

2. Google Charts: This gallery of interactive charts and data visualisation tools makes it easy to embed visualisations within your portfolio using HTML and JavaScript code. A robust Guides section walks you through the creation process.

3. Datawrapper: Copy and paste your data from a spreadsheet or upload a CSV file to generate charts, maps, or tables鈥攏o coding required. The free version allows you to create unlimited visualisations to export as PNG files.

4. D3 (Data-Driven Documents): With a bit of technical know-how, you can do a lot with this JavaScript library.

5. RAW Graphs: This open-source web app makes it easy to turn spreadsheets or CSV files into a range of chart types that might otherwise be difficult to produce. The app even provides sample data sets for you to experiment with.

Bonus: End-to-end project

There鈥檚 nothing wrong with populating your portfolio with mini-projects highlighting individual skills. But if you鈥檝e scraped the web for your own data, you might also consider using that same data to complete an end-to-end project. To do this, take the data you scraped and apply the main steps of data analysis to it鈥攃lean, analyse, and interpret.聽

This can show a potential employer that you not only have the essential skills of a data analyst but that you know how they fit together.
