Data Scientist

An individual who collects, analyzes, and interprets extremely large amounts of data is referred to as a data scientist. A data scientist is an offshoot of a number of traditional technical roles, including mathematicians, scientists, statisticians, and computer professionals. Advanced analytics technologies, such as machine learning and predictive modeling, are required for this job.

In order to form hypotheses, make inferences, and analyze customer and market trends, data scientists require large amounts of data.  In order to detect patterns, trends and relationships in data sets, the analyst gathers and analyzes data using various types of analytics and reporting tools.

The goal of data scientists in business is to mine big data for information that can be used to predict customer behavior and identify new revenue opportunities. Additionally, data scientists are often responsible for establishing best practices for collecting data, analyzing data, and interpreting it.

Big data, the voluminous amounts of structured, unstructured, and semi-structured data that large enterprises and internet of things collect, have increased demand for data science skills over the years.

What is the importance of data science?

As an interdisciplinary field that involves a wide range of information, data science typically looks at the big picture more than other fields of analysis. Businesses use data science to gather intelligence about their customers and campaigns and to create strong plans to engage and sell to them.

Using big data, the large amounts of information collected through multiple collection processes, such as data mining, data scientists must develop creative insights.

A business’s long-term success can also be determined by understanding its customers, who ultimately determine the success of the business. Data science can help companies control their brands’ stories in addition to targeting the right audience.

There are constantly new tools available in the field of big data, and experts who understand the applications of those tools are needed. Companies can work with data scientists to create a business plan based on research rather than intuition to achieve their goals.

Since data science allows for drilling down into data to find slight irregularities that can expose security weaknesses, it plays an important role in security and fraud detection.

Through personalization and customization, data science creates highly specialized user experiences. Customers can feel heard and understood by a company using the analysis.

 

Responsibilities and roles

Scientists and mathematicians, statisticians, chemometricians and computer scientists are some of the most important technology fields today. It is rare to find a data scientist with the right combination of personality traits, experience, and analytics skills, so there is a high demand for qualified candidates.

In 2016, 2017, 2018 and 2019, data scientists topped Glassdoor’s list of “50 Best Jobs in America” based on job satisfaction, number of job openings, and median salary. It is possible to find data scientist jobs advertised as machine learning architects as well.

Analyzing large quantitative and qualitative data sets is one of the basic responsibilities. Statistical learning models are developed for data analysis by these professionals, who need to be familiar with statistical tools. To create complex predictive models, they must also possess the necessary knowledge.

In addition to computer scientists, database programmers and librarians, disciplinary experts, curators, and expert annotators, data scientists can also be full-time data scientists. It is also possible to find job postings for data scientists advertising the position as “machine learning architect” or “data strategy architect.”

The characteristics

Intellectual curiosity combined with skepticism and intuition, as well as creativity, are soft skills necessary for this role. The role involves regular interaction with many teams, so interpersonal skills are crucial. Employers tend to look for data scientists who are strong storytellers who can communicate data insights to people across the organization at all levels. To steer data-driven decision-making processes in an organization, they must also possess leadership skills. Managing the massive amount of data required for predictive analytics also requires business savvy, leadership, and the ability to predict risks.

Skills and qualifications required

In order to perform a wide range of extremely complex planning and analytical tasks in real time, data scientists need adequate educational or experience backgrounds. A bachelor’s degree in a technical field is required for most data science roles, regardless of which jobs require specific qualifications.

Big data platforms and tools, such as Hadoop, Pig, Hive, Spark and MapReduce, as well as programming languages such as SQL, Python, Scala and Perl, and statistical computing languages, such as R, are required for data science.

Data mining, machine learning, deep learning, and an ability to integrate structured and unstructured data are hard skills required for the job. As part of the role, you’ll also need to have experience with statistical research techniques, such as modeling, clustering, data visualization, segmentation, and predictive analysis.

The following skills are typically listed in job postings:

  • An understanding of all phases of data science, starting with discovery, cleaning, selecting models, validating them, and deploying them;
  • Data warehouse structure knowledge and understanding;
  • Ability to solve analytical problems using statistical approaches;
  • Expertise in common machine learning frameworks;
  • Platforms and services offered by the public cloud;
  • Understanding of 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 improve business processes through the use of machine learning;
  • The ability to create and implement dashboards that measure key business metrics and provide actionable information;
  • Expertise in quantitative and qualitative analysis techniques;
  • Ability to communicate qualitative and quantitative analysis in an understandable manner;
  • K-nearest neighbors, Naive Bayes, random forests, and support vector machines are some examples of machine learning techniques;
  • Validation tests must be designed and implemented;
  • The degree must be advanced with a specialization in statistics, computer science, data science, economics, mathematics, operations research, or another quantitative area;
  • Visualization experience using Tableau or Power BI;
  • Coding skills, including R, Python, and Scala;
  • The ability to aggregate disparate sources of data; and
  • Performing ad hoc analyses and presenting results clearly is a must.

 

Certifications, education, and training

Statistics, data science, computer science, or mathematics are typically the education requirements for data scientists. Certifications available for this role include Dell EMC DECA-DS, MCSA: Various SQL/Data Engineering Options, Microsoft MCSE Data Management and Analytics, and Certified Analytics Professional.

Six major areas of data science

Data science can be divided into six main areas:

 

  • Investigations involving multiple disciplines. Data scientists collect large amounts of data using a variety of methods when working with large, complex systems.
  • Methods and models for analyzing data. Modeling data requires experience and intuition, and data scientists must constantly adjust their methods to gain the insights they seek.
  • This is pedagogy. To collect and analyze information about their customers and products, data scientists must work with companies and clients to determine the best ideologies.
  • Data processing. Due to the vast amount of information they are working with, all data science projects require tools and software to analyze the algorithms and statistics involved.
  • Theory. With countless applications, data science theory is a rapidly evolving and sophisticated professional field.
  • Evaluation of tools. Data scientists have access to many tools for manipulating and studying huge quantities of data, and continually evaluating their effectiveness and using new ones is vital.
