In general, data scientists design and develop new processes for data production and modeling. Apart from interpreting and performing product experiments and data studies, these people are tasked with developing predictive models, prototypes, algorithms, and custom analysis. They also need to be able to work with a wide range of techniques to deal with data including machine learning and data mining. To be able to perform all these, holding advanced degrees like a master’s or Ph.D. is crucial to becoming a successful data scientist.

2- Data analyst
