Being a data analyst in 2024 is one of the most promising career options, given the rising demand for individuals possessing strong analytical skills. However, looking at the excessive amount of resources available on the internet, one can easily get lost on where to start and learn the necessary skills. This blog will cover a simplified and structured approach one can follow as a beginner to become a proficient data analyst in 2024.
Who is a Data Analyst?
A huge amount of data is generated every minute. Companies seek skilled data analyst professionals who can collect, organize, and effectively analyze this data to provide valuable insights on how to tackle similar challenges in the future.
Data analysts work collaboratively with data scientists and data engineers to make data-driven decisions that benefit the company.
Roles and Responsibilities of a Data Analyst
In a typical day, the life of a data analyst revolves around collecting data from different sources, cleaning and organizing data, performing exploratory data analysis, and creating visualizations to identify trends and patterns. The next step involves extracting insights from the data and presenting these findings to stakeholders to determine what is best for everyone. Here, effective communication skills play a pivotal role, as this defines your ability to convey the results to the stakeholders.
The better the communication, the better the decisions will be. Data analysts are always open to learning new skills to apply the best possible analysis to their data.
How to become a Data Analyst
1. Tools and Programming Languages
First and foremost, let’s talk about the tools that a data analyst uses daily at work for data analytics processes such as collecting, analyzing, visualizing, and reporting data. I have listed these tools without any specific order in mind, and you can learn them all gradually as your journey progresses. Remember this key principle: focus on one thing at a time.
As a data analyst, a significant portion of your work involves working with huge databases. SQL, or Structured Query Language, serves as the primary tool for accessing, storing, and analyzing information within these databases effortlessly. SQL provides advanced query functions, which allow you to extract specific data and draw conclusions from it.
Python or R
Python and R are popular programming languages used for data analysis processes. Depending on your preference, you can opt to learn either one of them or both. Python is often preferred by beginners due to its relatively simpler syntax, which sets a strong foundation for getting started. R provides a more streamlined approach for statistical analysis and data visualization, with packages like ggplot2, and is used mostly by data scientists.
While Python libraries like NumPy and Pandas are used for exploratory data analysis, other libraries, including Matplotlib, Seaborn, and Plotly, are used to create beautiful visualizations. Learning these libraries will not take much of your time and will make your analysis much easier, setting you apart from the rest of the crowd.
Tableau or PowerBI
While you can easily visualize data using the various libraries mentioned above, when working as a data analyst, you are expected to present comprehensive reports of your analysis. Popular dashboarding tools like Tableau and PowerBI are used for this purpose, which are known for their user-friendly drag-and-drop interfaces and extensive customization features.
Data analysts utilize them to transform their raw analysis into interactive dashboards that can be presented to stakeholders. Both Tableau and PowerBI are prominent tools and are easy to learn, so getting used to both of the tools can be advantageous for anyone getting into this field. For an in-depth comparison, refer to this blog.
The Microsoft ecosystem requires no introduction. Microsoft Excel is known for its powerful numerical and statistical analysis proficiency on spreadsheets. It is the fundamental tool for organizations that use it for data collection, analysis, and manipulation. Learning advanced Excel functions like CONCATENATE, SUM, AVERAGE, ROUND, SUMIFS, COUNTIFS, IF/ELSE analysis, VLOOKUP, and pivot tables will help you a lot in your day-to-day analysis tasks.
Additionally, real-time collaboration tools like Google Sheets, which offer flexibility to teams within an organization, can be a valuable addition to your resume.
Last but not least, a strong knowledge of statistics can really help in selecting the most relevant parameters to make the most of the analysis, which will subsequently help you conclude with meaningful insights and find trends and patterns in the data.
One should have a knowledge of basic statistical concepts, such as the distinction between inferential and descriptive statistics, probability, significance of hypothesis testing, distribution of data, skewness, variation, and standard deviation.
2. Build A Strong Portfolio
Learning the skills is one thing; applying them is another. Knowing how to apply the tools mentioned above to practical use cases is an indicator of how well you have mastered all these tools and technologies.
Here are some tips to build a strong portfolio that will significantly increase your prospects of securing a job as a data analyst:
