Data Scientist: King of Data!!

Who is Data Scientist?
A Data Scientist is a person who is in charge of gathering, analysing, and interpreting massive volumes of data. Mathematician, scientist, statistician, and computer professional are all examples of old technical jobs that have evolved into Data Scientists. Advanced analytics technologies, such as machine learning and predictive modelling, are required for this position.
To create hypotheses, make conclusions, and evaluate consumer and market trends, a Data Scientist needs a lot of data. Gathering and analysing data, as well as employing various forms of analytics and reporting tools to discover patterns, trends, and correlations in data sets, are all basic tasks.

Why is Data Science important?
Data Science is a highly multidisciplinary area that deals with a wide range of data and, unlike other analytical areas, tends to focus on the big picture. The objective of Data Science in business is to offer knowledge on customers and campaigns, as well as to assist firms in developing solid plans to engage their audiences and sell their products.
Big data, or enormous volumes of information acquired through various collecting techniques such as data mining, requires Data Scientists to rely on innovative ideas.
On a more fundamental level, big data analytics may assist companies in better understanding their consumers, who ultimately decide a company’s or initiative’s long-term success. Data Science may be used to help firms control their brand narrative in addition to targeting the correct audience.

Skills required for being a Data Scientist:
• knowledge and understanding of common data warehouse structures;
• experience with using statistical approaches to solve analytical problems;
• proficiency in common machine learning frameworks;
• experience with public cloud platforms and services;
• expertise in all phases of Data Science, from initial discovery through cleaning, model selection, validation, and deployment;
• familiarity with a wide range of data sources, including databases, public or private APIs, and standard data formats such as JSON, YAML, and XML;
• ability to identify new opportunities to apply machine learning to business processes to improve their efficiency and effectiveness;
• familiarity with machine learning techniques such as K-nearest neighbours, Naive Bayes, random forests, and support vector machines;
• ability to design and implement validation tests;
• experience with qualitative and quantitative analysis techniques;
• ability to share qualitative and quantitative analysis in a way that the audience will understand;
• advanced degree with a specialisation in statistics, computer science, Data Science, economics, mathematics, operations research, or another quantitative field;
• experience with visualisation tools like Tableau and Power BI;
• coding skills like R, Python, or Scala; and
• ability to conduct ad hoc analysis and present results in a clear manner
Responsibilities of Data Scientist:
On any given day, a Data Scientist’s tasks might include:
• Undirected research to solve business issues and formulating open-ended industry inquiries
• Extraction of massive amounts of organised and unstructured data
• They use computer languages like SQL to query structured data from relational databases.
• Web scraping, APIs, and surveys are used to collect unstructured data.
• Prepare data for predictive and prescriptive modelling using advanced analytical tools, machine learning, and statistical approaches.
• Clean data thoroughly to remove unnecessary information and prepare it for pre-processing and modelling.
• Discovering novel methods to address issues and building programmes to automate repetitive labour
• Communicating forecasts and results to management and IT departments through excellent data visualisations and reports
• Make cost-effective modifications to existing methods and tactics.

Data Scientist Qualifications
• Programming abilities
Candidates for Data Science jobs should be able to demonstrate a mix of python and R programming skills, as well as knowledge of Hadoop, SQL, and machine learning/AI methods.
It’s not unusual for Data Scientists to have a portfolio ready to show off their expertise in these areas, much as software developers.

• Interpersonal abilities
Recruiters search for soft skills in Data Scientist applicants such as communication, presentation abilities, and multi-functional teamwork.
Recruiters are always on the lookout for Data Science candidates that can convert large data into a storey that the rest of the organisation can understand.

• Visualization of data
While not programmatic, a thorough grasp of data visualisation tools like as Tableau and Chartist is critical to a Data Scientist’s success and a must-have on the Profile.

• A business plans.
Data Scientists give data meaning.
For recruiters looking to employ Data Scientists, demonstrating a better grasp of a company’s business goals—and how that may be demarcated using big data—is a bonus.

Roles of Data Scientist:
• Collaborate with internal stakeholders to discover opportunities to use corporate data to create business solutions.
• Analyse and optimize product development, marketing tactics, and commercial strategies by mining and analyzing data from company databases.
• Evaluate the efficacy and precision of new data sources and data collection procedures.
• Create bespoke data models and algorithms for use with specific data sets.
• Increase and improve customer experiences, revenue generation, ad targeting, and other business results by using predictive modeling.
• Establish a company-wide A/B testing strategy and evaluate model quality.
