The amount of information in the modern world is growing exponentially every day. Businesses use the data collected from their websites, customers, sales, social media, and general operations to make wiser, data-driven decisions. These are the people responsible for transforming piles of information into something meaningful: data analysts. Due to the importance and high demand for such specialists, this career is an attractive choice for job seekers and students who want to change their careers.
Know What You Are Getting Into
Before starting your journey in the world of data analytics, you should know what it is you are getting into. Basically, data analytics involves collecting, storing, analyzing, and presenting information. The data analyst’s job is to ask the right questions and find answers to help businesses make better decisions. Of course, every company has certain needs, but most analysts face similar problems.
Learn Excel
Microsoft Excel is one of the most useful and popular programs among data analysts. First of all, you need to study Excel formulas, functions, sorting, filtering, conditional formatting, pivot tables, charts, and graphs.
Learn SQL
Structured Query Language, or SQL, is a programming language needed almost by any company that deals with data. Analysts work with databases containing all sorts of information, which they have to process and analyze. You need to learn basic SQL queries, including SELECT, WHERE, GROUP BY, ORDER BY, JOIN, and aggregate functions, among others. Knowing SQL will give you a solid foundation for working with databases.
Learn python
Python is a great programming language for data analysts since it helps automate repetitive tasks, write scripts for data processing, and analyze data sets. You will also need Python libraries for statistical analysis and data visualization. Start with Pandas and NumPy, and then move on to visualization tools.
Get Hands-On Experience and Do Projects
In addition to theoretical knowledge and Excel skills, every analyst needs to know how to work with Python, SQL, and data visualization tools. The best way to learn is by doing real projects. You will find many data sets on the web that you can use for practice. For instance, you can work with sales data sets and visualize this information. You can also analyze the sales data set and make presentations or reports based on your findings and conclusions. Check out some of the following helpful resources on Medium, Kaggle, and Towards Data Science.
Make a Portfolio
A portfolio is a collection of projects that demonstrate your skills and serve as evidence of your abilities when on the job market. Your portfolio should contain your best works related to data analytics, including Excel, Python, and SQL projects, as well as charts created with Power BI or Tableau. Additionally, you should also describe the project, the data set, the techniques you have used, and the results and conclusions you have reached. You can host your portfolio on GitHub, a blog, or your LinkedIn page.
Get a Job as a Data Analyst
Once you have gained enough experience, it is time to start looking for a job. Most companies are looking for junior data analysts, analysts, reporting analysts, business analysts, or data analyst interns. Be sure to customize your resume according to the position you are applying for, emphasizing the skills and projects that match the job description. Moreover, prepare for interviews by practicing SQL queries, Excel tasks, statistical problems, case studies, and questions about the projects in your portfolio.
Conclusion
Becoming a data analyst demands inquisitiveness, practice, and learning. The onus is on you to start practicing excel, statistics, and SQL before advancing to python and visualization. It is paramount to grow your skill set, work on practical life projects, and build your portfolio to land your first data analyst job. Moreover, it is essential to prepare for interviews and applications to increase your chances for employment. With these skills and practical knowledge, good luck in becoming a data analyst in a data-driven world.
