What Tools Do I Need To Get Started?

Data Scientists work with some of the latest technology including artificial intelligence and machine learning, as well as programming languages that constantly evolve. It is therefore essential that Data Scientists understand how to make the most of the tools that enable Data Scientists to gather, clean, sort, analyze, and make sense of data. Tools commonly used by Data Scientists include: 

• Python programming
• SQL 
• Data visualization tools

Python

Understanding Python programming is key to becoming a Data Scientist. Data Scientists use Python to gather data, automate tasks, improve data collection processes, create data visualizations, and more. Python is an open-source programming language, meaning that it is free for anyone to use. This means you can access the latest version of Python and Python libraries at no cost. Python also enjoys an active group of supporters who help one another learn best practices, make recommendations for improvements to the language, and more. While Python is considered one of the easier programming languages to learn, it helps to learn from an instructor who can provide step-by-step guidance, answer questions, and help you learn through hands-on activities. 

SQL

Standard Query Language (SQL) allows Data Scientists to explore databases and retrieve data from them. It also allows Data Scientists to filter, sort, and group data to identify information that helps an organization achieve its goals. There are both free and paid SQL tools available. 

Data Visualization Tools

Data visualizations make it easier for stakeholders to see patterns and understand the state of the data. Examples of data visualizations are graphs and charts. Data Scientists use the Python library Matplotlib and the software tool Tableau to create interactive dashboards and data visualizations. Knowing how to create a data visualization enables a Data Scientist to plan and present data stories, assemble data from various sources, manipulate data, enhance presentations, and more. Matplotlib is a free Python library. Tableau offers a free version of the software called Tableau Public.

Steps to Become a Data Scientist

If you are interested in starting a career as a Data Scientist, you will want to outline the steps needed to meet your goal. This includes outlining your career goals, identifying the right learning method, dedicating time to learning the necessary skills, creating a professional portfolio, networking with others in your field of interest, and starting your job search. 

Determine Your Goals and Learning Path

The first step toward starting a career as a Data Scientist is to identify your career goals and learning path. Is there a particular area of data science you wish to specialize in? What skills do you need to become a Data Scientist? Data Scientists must understand how to use data management and visualization tools, how to use machine learning to process data and forecast outcomes, and how to use R programming, Python, Java, and sometimes other programming languages such as C++. Identifying the skills necessary to reach your career goal will help you determine what learning method to pursue.

How do you go about learning data science skills? While earning a four-year degree related to data science is an option, it is a costly and time-consuming one. Most working professionals wishing to launch a new career as a Data Scientist learn data science skills through on-demand classes, in-person classes, or live online classes. On-demand classes such as those found on Skillshare and LinkedIn Learning provide the most flexibility since you can stop and start the course whenever you choose. The major drawback to the on-demand/self-paced learning method is the lack of access to an instructor if you have questions. In-person classes are those taught by an expert instructor in a physical learning location, allowing you to network with local professionals such as your classmates.

In-person learning works well for those who prefer face-to-face, and it provides access to all necessary equipment and software. In-person classes also incorporate hands-on assignments that help you retain what you learn, develop your skills, collaborate with others, and build a professional portfolio. The major drawback to in-person classes is the extra time and expense that commuting to the class requires. 

Live online learning offers many of the same benefits as in-person learning including real-time feedback from your instructor, the ability to collaborate with classmates, and the use of hands-on assignments. Live online classes have the benefit of letting you learn from anywhere. Virtual classes do, however, require that you have the necessary software and tools needed for you to learn. Remote learning may also mean that your classmates do not live in your local area, so the class may not provide the chance to network locally.

When deciding which learning method works best for you, keep both your budget and learning preferences in mind. If you want to start learning data science skills before committing to a paid learning method, you can explore free learning tools through Noble Desktop’s Data Science Learn Hub.
