5 Popular Data Science Careers That Are in Demand

What is Data Science?

Data science is the practice of working with information in a way that turns raw numbers into meaning. 

It uses test hypotheses and algorithms to examine information such as:

- What happened
- Why it happened
- What will happen, and
- What actions should be taken

Nowadays, it integrates advanced techniques like:

- Descriptive analysis
- Diagnostic analysis
- Predictive modeling, and 
- Prescriptive analytics

The data science process is defined by frameworks such as OSEMN (Obtain, Scrub, Explore, Model, and Interpret). It guides professionals from initial data cleaning to final data visualization and presentation.

How an Online Master’s in Data Science and Analytics Helps

Most employers look for highly skilled and educated candidates with advanced degrees in data science. 

An online master’s in data science and analytics provides that balance. It covers subjects like:

- Machine learning
- Predictive modeling
- Advanced programming
- Data engineering 

Online educational programs are excellent for working professionals because they help them keep learning new technologies while still managing their full-time jobs.

A degree in data science gives you the chance to work on real projects, tackle case studies, and build a portfolio that shows employers you can actually put your skills to use.
