What is Data Science?
Data science is a broad field that encompasses the disciplines of mathematics, computer programming, and artificial intelligence (AI). Data professionals such as Data Scientists and Data Analysts use advanced techniques like machine learning algorithms to find patterns in a vast amount of information. This process can provide actionable insights to stakeholders, from Product Managers to C-suite executives.
Today nearly every sector requires data science expertise, whether public or private. Among the top sectors where data science is critical are health and wellness, retail, web and application development, banking and finance, and governmental agencies. The field continues to project dramatic growth over the next decade; Glassdoor even listed Data Scientist as number three in its 50 Best Jobs in America in 2022.

What Can You Do with Data Science?
Data science has so many applications in different industries that a comprehensive review could fill a book. Professionals as diverse as Business Analysts, Machine Learning Engineers, and Enterprise Architects use data science in their day-to-day activities.
Top sectors for data science include banking and finance, marketing and advertising, and healthcare:
- Banking, Financial Services & Insurance (BFSI) - Business Analysts and Data Scientists use data for everything from fraud detection to customized financial advice. Machine learning algorithms can assist with risk analytics, stock trading, and other tasks.
- Marketing & Advertising - Data Analysts and Marketing Analysts use data science in advertising to create targeted ad copy, recommend products and services, and leverage social media platforms. Programming languages like Python and R, often key to data science positions, help experts analyze data and make recommendations.
- In healthcare, Data Scientists create algorithms to create care plans and improve patient services. Using data analysis in medical imaging can help care providers with diagnoses and treatment decisions.
Data science has proven crucial to many other sectors, from retail and manufacturing to the public sector. If you want to combine challenging work with job security, start with data science.
In-Depth Review of the Cost
Detailed pricing for data science training truly depends on what you need to learn. The tools and skills required for a Business Intelligence (BI) Analyst can differ considerably from those of a Data Scientist. Check online job postings for requirements to understand where you need basic skills and what you need to master in great detail.
Several tools and skills that apply to data science and analytics offer free or inexpensive limited trials. Consider the following:
- Tableau - Salesforce, which offers this popular data visualization tool, allows students and teachers a free, 1-year license. For others, their tiered pricing options start as low as $5/month for self-paced learners and run as high as $70/month for the feature-rich Tableau Creator subscription.
- Python - As mentioned above, Python’s software, libraries, and frameworks are available free of charge. Thanks to its worldwide support community, it’s possible to learn some Python fundamentals for little to no money. Check out the free online tutorials in Noble Desktop’s Learn Hub to learn more.
- SQL - Along with Python, SQL (Structured Query Language) remains one of the top languages for Data Scientists and Data Engineers. You can learn more about SQL with the free online Intro to SQL course from Noble Desktop.
Why Learn Data Science?
Your path to learning data science tools and languages depends heavily on how and where you plan to use your knowledge and skills. A Data Scientist or Data Analyst will need comprehensive training in math, computer science, probability, and statistics. However, a Back End Developer may need only a few tools applicable to data science, like Python and Django REST.
The most significant benefit to learning data science skills and tools is the breadth of their applicability. A top programming language like Python will be crucial in fields like machine learning (ML) or artificial intelligence (AI). At the same time, data visualization tools like Tableau can be essential for everyone from Business Analysts to SQL Server Developers.
Whether you plan a role as a Cybersecurity Analyst, a Machine Learning Engineer, or a Business IT Analyst, data science skills will prepare you to analyze information, gain insights, offer conclusions, and even make predictions.
