Data Science Job Roles and Responsibilities
Data scientists are responsible for identifying patterns and exploring the deepness of immense quantities of raw data that can either be structured or unstructured, to help fulfill certain organizational needs and goals. The data scientist role is becoming crucial in sustaining modern-day businesses' needs. Today's businesses depend on data analytics for effective decision-making using key aspects of neural networks and deep learning.
ROLE OF DATA SCIENTIST:
A data scientist’s primary aim is to organize and study heavy amounts of data, using methodologies specifically introduced for these tasks. The outcomes of a data scientist’s analysis must not include too many technical details and need to be simple enough for all concerned stakeholders including those who don't belong to the IT department.
A data scientist’s proceedings towards data analysis depend on the organization they are linked with. Main business drivers must make it manifest what they’re heading for before a data scientist can provide meaning to raw data. Then, a data scientist's role comes into action. They must have enough business-oriented expertise to interpret business goals into data-based, case-based, or knowledge-based deliverables such as prediction engines, pattern identification analysis, optimization methodologies, etc.
RESPONSIBILITIES AND DUTIES:
A data scientist’s primary job is data analysis. Data analysis is a process that starts with data gathering and ends with business decisions made based on the final data analysis reports by data scientists.
Nowadays, there is a huge amount of data that data scientists can analyze and is called big data. Two types of data lie under the category of big data:
Structured data: It's a well-shaped form of data concerning categories that make it feasible for a computer to sort and read smartly. This organized form of data includes data collected by services, products, and electronic devices, but hardly any data contributed by a human. Website traffic insights, sales charts, bank transactions, etc. are structured forms of data.
Unstructured data: It is the most accelerating form of big data. It is more likely to produce after human contributions like customer reviews, emails, and social media trending, etc. It is very difficult to sort this type of data and manage it with computer systems. Because unstructured data isn’t categorized and organized, it requires a huge investment to shape it into a useful form. Businesses typically depend on keywords or key phrases to make unstructured data intelligible to filter out useful and relevant information using searchable terms.
Almost all business facilities recruit data scientists to tackle unstructured data, whereas other IT experts can be hired for managing structured data. It means, data scientists most likely deal with a lot of unstructured data throughout the career, as business dependencies to induce unstructured data in operation to meet revenue goals are continuously escalating.
Data science is a fast-growing field and promises data scientists a satisfying and long-term career. Data scientist role ranked as the best job based on several vacancies, salary packages, and overall job ratings on different forums.
A percentile is a measurement aspect used in statistics referring the value with a given percentage of observations in a group of observations falls, the average salary for data scientists Robert Half's 2018 Technology and IT Salary Guide, based on experience, has following percentile breakdowns:
