What Is Data Science?
Let’s start with the basics.
Data Science is the science of data. This may involve gathering, cleaning, and analyzing data to get actionable results. Businesses use this to make savvy decisions, like what products to sell and which customers to target, among other things.
Data Science includes:
- Math & Statistics
- Programming (mostly Python)
- Machine Learning
- Data Visualization
- Big Data Tools
Even though that might sound like a lot, it’s not. You needn’t learn everything on day one. You can begin with simple online courses that teach from absolute zero.
Why Learn Data Science in 2025?
The truth is, that data is all around us these days. Every second, data is being used by companies, schools, hospitals, apps — even games.
Here’s my take on why learning data science is awesome:
- High salaries: Data scientists are paid more than other IT jobs.
- Work-from-home friendly: You can work from a laptop.
- No coding required: Some tools offer instruction in data science concepts without requiring coding.
- Skill of the future: In demand even 10 years from now
