I am not a data scientist but in my job I have worked with a few. The data scientist found correlations between multiple data-sets to help our company adjust our strategy after introducing a new product. On the team some of the members were data scientists but many had a few of the "Skill Set's" mentioned below and were learning "On the Job". I hope this helps.
I found this information https://www.discoverdatascience.org/career-information/data-scientist/
Majors for data science are statistics, computer science, information technologies, mathematics, or data science (if available). Minoring in one of the aforementioned fields is also recommended.
Data Scientist Skill Set
- Experience and Fluency in many of these computer/coding programs: SAS, SPSS, MATLAB R, Python, Java, C/C++, Hadoop Platform, SQL/NoSQL Databases.
- Business Savviness: Data scientists need to understand the business sector they are working in and create solutions to complex problems that align with business logic/objectives.
- Communication skills: A data scientist can clearly and fluently translate their technical and analytical findings to a non-technical department. They must also be able to understand the needs of their non-technical departments (such as business development or marketing teams) in order to analyze the data correctly. A data scientist must empower the business to make decisions by presenting robust and verifiable information.
- Expert Technical skillsin the following:
- Math (g., linear algebra, calculus, and probability)
- Machine learning tools and techniques
- Data mining
- Data cleaning and munging
- Data visualization and reporting techniques
- Unstructured data techniques
