According to IBM, poor data quality costs the US economy around $3 trillion each year. Globally, that figure could be as high as $14 trillion. The demand for data scientists has soared in recent years. Data scientists are highly skilled professionals who use cutting-edge technology to make sense of large, often unstructured, datasets. They are necessary for almost every industry to help provide analysis for a data-driven business environment. They use proven strategies such as:
- clustering
- artificial intelligence
- behavioral analytics
- data mining
Earning an online data science PhD can give data scientists the professional skills needed to advance their careers.
