As a career path for highly skilled professionals, data science is proving to be one of the most exciting and in-demand. Data professionals are now able to go beyond the traditional skills of data analysis, data mining, programming, and program development. Data scientists need to be able to understand and master all phases of data science in order to find useful intelligence for their companies.
Data scientist was first used in 2008, when companies recognized the need to have data scientists who can organize and analyze large amounts of data. Hal Varian, Google’s chief economics and UC Berkeley professor information sciences and business, discussed the importance of adapting technology’s influence on different industries.
Data scientists can identify and answer relevant questions, gather data from many sources, organize it, make sense of the results, and then communicate them to business leaders. This skill is required by almost every industry, making data scientists more valuable for companies.
