How to Become a Data Analyst

Becoming a data analyst entails following different paths that will enable one to have the required skills for this growth in this chosen career area. However, for the sake of this post, some key steps to follow so that one can become a data analyst will be discussed in great depth. This is because, for most people who are passionate about this career path, the question of ” how to become a data analyst can often be challenging.”

To make one easily resolve this, this post will attempt to show you some steps that you can take to become a data analyst. These steps include: 

Step 1. Know the Basics of Data Analytics

The first step to becoming a data analyst is to know the basics; this entails understanding the use of data analysis tools such as programming languages like SQL, Python, and R and even advanced Microsoft Excel. Other areas to become familiar with are using tools like Spark and Hadoop for number-crunching and creating beautiful visualizations that make one’s data come alive. The knowledge of Tableau, Matplotlib, or ggplot2 will come in handy. 

One easy way to learn these basics is through data analysis courses, which give you the platform and opportunity to become grounded in these skills. You also gain hands-on experience in the usage of programming languages, statistical programming, data management, data cleaning, and visualization by using these data analysis courses. Most of these often operate like a school academy, making data analysis way so interesting, unlike following only tutorials.

Step 2. Take a Certification or Do Projects to Build Your Skills in Data Analysis

Having understood the basic data analysis tools, you can take up projects that will allow you to put your knowledge to work. To be successful as a data analyst, you will need to keep up with the latest trend and updates of tools used with data analysis. This includes; visualization tools like Tableau, PowerBi, Plotly, and Matplotlib; spreadsheets and querying languages like XML and SQL and even programming languages like Python and R. 

One will also need to have experience with analytics platforms such as Google Analytics. Then you can take this knowledge to another level by putting together practice projects that cut across various areas of data analysis, including the research of the companies and the market opportunities; understanding the scope for the data that needs to be collected, cleaning the data, and then making models and analysis of the collected data using custom-built algorithms. Thereafter, one can put together the data’s findings into visible and beautiful visualizations that allow people to understand your result. One can also choose to use a dashboard that allows others to use your dataset in a user-friendly manner.

By constantly taking up practice projects of this nature, you will ultimately grow and improve your data analysis skills. Also, try to make your practice projects involve different datasets, including structured and unstructured data, data sets involving images and texts, etc. Also, try to perform statistical predictions based on these data sets.

Also worthy of note is the need to pick up certain soft skills along the line as you practice your data analysis skills. These soft skills will make you stand out from other data analysts, and they include; creativity and communication skills,  paying attention to details, analytical and statistical skills. Invariably, you will grow and excel faster in your career path as a data analyst as you imbibe and embrace these soft skills. 

Step 3. Create Visualization and Work on Their Presentations 

Visualization tools like Tableau, Matplotlib, or PowerBi help you make your data presentable to others so they can easily interact with it. Practicing these tools and trying to build your visualizations from scratch so your data can be easily interpreted and understood by others.  Another tool that comes in handy here is Excel, even though it is basically for spreadsheets, using the information in cells to correlate a graph or make suitable calculations. Yet, it is a major tool that helps make visualizations easy and highly unavoidable in data science. 

Apart from just creating visualizations, one should properly understand these visualizations to present your findings as a data analyst. This is where having communication skills comes in handy. You can learn and even practice becoming good at making your presentations as you grow in your communication skills. It’s just that simple; start by presenting to someone, maybe a friend or a colleague, and after a while, you can take on a larger crowd. By so doing, you will grow in your presentation and communication skills. 

Step 4. Build a Portfolio of Your Data Analysis Projects to Display Your Skills

As a data analyst, people will only know how good you are from your past or current projects on display. This is where an online portfolio comes in handy. The codes you have written in your practice projects can be put on GitHub to serve as your portfolio on display. This can temporarily showcase your project work to others before you build a professional portfolio page or website. 

Also, being a part of online data science networks like Kaggle and Zindi will help create the platform for you to project your skills as a data analyst. These networks will also enhance your skills through data science competitions, which will continue to grow your expertise and outreach. Eventually, you will show to the world your strides in data science as an aspiring data analyst.

Again, you can show your skills and abilities as a data analyst by working on a well-executed project to solve a particular problem through the field of data science. Just look for a problem or need that interests you and start working on it. Along the way, ask questions, and if you are stuck, you can always refer to Google or Stack Overflow to help you out. Let your solution be an answer to a question of interest.

  • Strong and Effective Communication Skills. To be a successful data analyst, one needs to communicate one’s findings to people easily and understandably properly. 

Relevant Tools Used for Data Analysis 

As an aspiring data analyst, it is important to know those tools that are often being used to gather, clean, and process data into a usable and easily accessible form. Some tools used by a data analyst are:

  • Tableau: A tableau is a tool that helps data analyst properly analyze data into well presentable forms. Through Tableau, one can produce dashboards that can be used by other team members and even create visualizations to display the findings from a data set.
  • Google Analytics Tool (GA): Understanding customer data, especially areas about trends and customer experience, is key to enhancing your analytics results as a data analyst. This is where the usage of GA comes in handy. This enables one to track customer experience areas that require improvement on landing pages and instigate necessary calls to action (CTAs).
  • GitHub: This is a project building and sharing platform for building technical projects for data analysts. This is especially handy for a data analyst who works with object-oriented programming (OOP). This platform also allows you to have a portfolio to showcase or display your data analyst projects’ codes for public view or prospective employers. 
  • Cloud Storage System (AWS S3): With large datasets, it is important to have a storage system to store and easily retrieve such datasets. This is where the use of Cloud storage systems like AWS S3 comes in handy. Data analysts often use them to hold and retrieve numerous datasets when needed from time to time. 
  • Jupyter Notebook System: A Jupyter notebook system is a software platform that makes testing of written codes easy for data analysis. As an aspiring and beginner data analyst, this platform helps you to easily write codes and make suitable changes to them because of its user-friendly interface, which also has a prominent markdown feature.  Therefore it is most preferred by non-technical individuals and also because of its simplicity in design.

The Salary Outlook for a Data Analyst 

According to the leading website authority, the average salary for a data analyst, “is $57,261”. More often than not, several factors account for changes in salary for different data analyst. These factors include the data analyst’s years of experience, his educational credentials, work experience with competent organizations, and even his certifications.
