Finally, we will talk about salaries for each of these specialties, and the differences between them:
According to Glassdoor, the average salary of a data scientist ranges from $ 113,436 to $ 123,000 per year, while a giant data expert has an average salary of $ 62,066, while a data analyst’s salary, according to the same site, is about $ 60,476 per year.
