Before we jump into the typical background needed, and educational requirements, let's address the one of the most frequent questions that aspiring data professionals are asking right now.
The simple answer to the question is: Yes.
While it is true that most organisations are looking for previous data skills and knowledge, it shouldn't stop you working toward your goal.
To become a data analyst without a degree, one must follow a clear plan and learning the necessary skills. The first step toward becoming a data analyst is to develop a career plan that defines specific goals and career timeline. This provides the opportunity to track progress and adjust as needed.
In one of our interviews, Elijah - a data analyst at Humana, shared his advice and steps to becoming a data analyst without experience:
First, you must learn the skills. I recommend learning SQL, Microsoft Excel, and a data visualization tool (Tableau or Power BI). Pick either Tableau or Power BI and stick with it. I usually suggest Tableau because it is easy to create and maintain a public portfolio. Some may suggest learning a more advanced tool like Python or R. However most entry level roles don’t require this experience, so I say focus on the above tools.
Second, build portfolios. This is especially important in the absence of a college degree. With or without a degree, a portfolio is the best way to prove you have used SQL, Tableau, etc. in an applied context. This step is incredibly important. Don’t skip it.
We will return to his advice again, but for now, remember - applying for entry-level data roles, even if one does not feel entirely qualified, demonstrating enthusiasm and skills, and showing a strong portfolio can increase the chances of success.
While there's no single educational path to becoming a data analyst, a certain level of formal education is often required.
A Bachelor's degree or a Master's degree in areas such as Computer Science, Mathematics, Statistics, Data Science, or Information Systems can often help you land a job as a data analyst. Certifications in specific areas such as Data Science, Business Analytics, SQL or other formal education in data can also be helpful in demonstrating your skills and expertise.
There are many online courses and bootcamps available to help you learn the technical skills necessary for a career in data analysis. Some popular options include Udemy, Coursera, DataCamp, and General Assembly. These platforms offer a range of courses, from beginner-level introductions to advanced data analysis skills.
You can also develop essential data analyst skills through self-study and learning resources such as books, blogs, and online forums. We also recommend engaging in Twitter and LinkedIn discussions, and deep diving into YouTube and Github, as great platforms to explore data science content, projects, and participate in communities of other data analysts.
To become a successful data analyst, you will need to develop a broad range of data skills. This section will cover some of the key areas to focus on, and what it takes to become, and really excel at your data analyst position. Remember, you don't need to master every skill before embarking on your journey to becoming a data analyst, but having a foundation in each of these areas will be helpful.
Technical skills are the foundation of data analysis. You will need to understand programming languages such as Python, R, and SQL, as well as tools like Excel and Tableau to collect, clean, explore, and analyze data.
Data analysts use a range of data analysis tools and technologies to gather, process, and analyze data. Some of the most common tools and technologies used by data analysts include:
Microsoft Excel: Excel is a powerful tool for data cleaning and manipulation. Data analysts use Excel to organize and clean data before analyzing it.
R programming language: R is a popular programming language used for statistical analysis. Data analysts use R to perform complex statistical analyses.
Tableau: Tableau is a data visualization tool that allows data analysts to create interactive dashboards and reports.
Python: Python is a versatile programming language used for web scraping, data analysis, and machine learning.
Apache Hadoop and Spark: Hadoop and Spark are big data processing and analysis tools used by data analysts to handle large data sets.
Industry specific tools, such as Google Analytics and Adobe Analytics
As the field of data analysis continues to evolve, new tools and technologies will emerge. Data analysts must stay up-to-date with the latest trends and tools to remain competitive in the job market.
Analytical skills are important for any data analyst, no matter the industry. You will need to be able to break down complex problems into smaller, more manageable parts and apply analytical skills to identify patterns and trends.
To improve analytical skills, some activities to consider include:
- Doing puzzles and brain teasers
- Participating in coding challenges on platforms
- Attending data competitions and events
Aside from technical skills, a successful data analyst must be able to communicate effectively. You will need to explain complex data analysis in a way that can be easily understood by stakeholders at different levels of an organization - in other words, you have to be able to bring data to life.
We've recently shared an interview with Ernie, who's a data manager at a biotech company, and he was highlighting the imporance of communicating clearly:
In my experience, one of the most important factors in a data-focused career is the ability to communicate with teams. When verbally describing reports, or large datasets, it is very difficult to conceptualize what someone might want. Don't be afraid to make mock reports and analyses just to make sure you're on the same page with the person requesting analyses.
Some tips to improve communication skills include:
- Practice speaking in front of an audience
- Take courses in public speaking or business writing
- Learn to use data visualization tools like Tableau or ggplot2 in R
- Ask for feedback on your presentations from colleagues or mentors
Having strong domain knowledge will help you add value to your analysis and recommendations. Depending on the industry or sector you're interested in, you can gain relevant knowledge through online courses, professional associations, and networking events.
Tisha - a data analyst at Tesla, shared the same sentiment in one of our interviews, how she builds her expertise and keeps up with the pace of changes:
To keep up with the ever-changing data analytics industry, I regularly attend industry conferences, participate in online courses and webinars, and engage in continuous learning through professional networking. Being part of data-driven communities and forums allows me to stay updated with the latest trends and best practices in the field.
Having a well-crafted portfolio can be an effective way to demonstrate your data skills and experience to potential employers. A portfolio can also showcase the projects you've worked on and the valuable insights you've gained through data analysis.
A portfolio serves as a reliable snapshot of your work and can help highlight your strengths, specific areas of expertise, and potential weaknesses. Hiring managers in the data analytics industry often look for samples of work that potential candidates have produced.
When building your portfolio, it's important to include a mix of personal and professional data projects. Personal projects can help showcase your passion and creativity and demonstrate your ability to work on your own. Professional projects can give hiring managers a glimpse into your previous work experiences and how you've been able to solve business problems through data analysis.
Some projects to consider adding to your portfolio include:
- Exploring publicly available datasets and identifying interesting patterns or trends
- Creating dashboards or visualizations that help clarify complex data insights
- Performing A/B testing and analyzing the results to improve a business metric
- Building a machine learning model that can automatically perform classification on a type of data
When you present your portfolio, it's important to highlight the thought process behind your projects and the techniques used to perform the analysis. Touch on which (if any) frameworks and tools you used, such as Python libraries or database querying tools, and why those were the best for the task at hand. Ensure your strengths and soft skills (communication, presentation, project management) are highlighted throughout the interview, and demonstrate your data analysis abilities.
