They’re a mix of mathematicians, computer scientists, and trend-spotters. They’re also in high demand and well-paid because they work in both the business and IT worlds. Who wouldn’t want to be a member of this elite group?

They’re also a reflection of the current era. Data scientists weren’t on many people’s radars a decade ago, but their rise underscores how corporations are approaching big data now.

That unmanageable jumble of unstructured data can no longer be overlooked. It’s a virtual gold mine that can help raise income – as long as someone digs in and uncovers business insights that no one else has considered. The data scientist enters the picture.

To build hypotheses, make inferences, and analyze customer and market trends, a data scientist needs a lot of data. Gathering and analyzing data, as well as employing various forms of analytics and reporting tools to find patterns, trends, and linkages in data sets, are all basic duties.

Data scientists in the business world usually work in groups to mine huge data for information that can be used to forecast customer behavior and uncover new income prospects. In many firms, data scientists are also in charge of establishing best practices for data collection, analysis, and interpretation.

Data science skills have become more in demand as businesses seek to extract meaningful information from big data, which refers to the massive amounts of structured, unstructured, and semi-structured data that a large corporation or the internet of things generates and collects.

Where did they come from?

A lot of data scientists started out as statisticians or data analysts. However, as big data (and big data storage and processing platforms like Hadoop) grew and expanded, so did those positions.

Data management is no longer an afterthought for IT. It’s critical information that necessitates in-depth study, imaginative curiosity, and a flair for turning high-tech concepts into new revenue streams.

The role of data scientist has academic roots as well. Universities began to notice a few years ago that companies sought programmers and team players.
Professors adjusted their curricula to accommodate this, and certain programmes, such as North Carolina State University’s Institute for Advanced Analytics, prepared to produce the next generation of data scientists. More than 60 universities throughout the country currently offer similar programmes.

Roles and responsibilities of Data Scientist

The term “data scientist” comes from a combination of science, math, statistics, chemometric, and computer science, to name a few of the most important modern technical subjects. Because the combination of personality traits, experience, and analytics capabilities required for this profession is uncommon, the need for skilled data scientists is on the rise.

Based on metrics such as job satisfaction, amount of job opportunities, and median base salary, data scientist topped Glassdoor’s list of “50 Best Jobs in America” in 2016, 2017, 2018, and 2019. A machine learning architect position may be listed with a data scientist job.

Analyzing huge data sets of quantitative and qualitative data is one of the most basic jobs. These individuals are in charge of creating statistical learning models for data analysis and must have prior knowledge with statistical tools. They must also possess the necessary skills to construct complicated predictive models.

Computer scientists, database and software programmers, disciplinary experts, curators, expert annotators, and librarians are some of the professionals who might work in data science or become full-time data scientists.

What’s in a data scientist’s toolbox?

Data scientists frequently use the following terminology and technologies:

Data visualization:

Data is presented in a pictorial or graphical format to make it easier to examine. The graphical representation of information and data is known as data visualisation. Data visualisation tools make it easy to examine and comprehend trends, outliers, and patterns in data by employing visual elements like charts, graphs, and maps.

Data visualisation tools and technologies are important in the Big Data environment for analysing enormous volumes of data and making data-driven decisions.

Machine learning:

Mathematics algorithms and automation are used in this branch of artificial intelligence. Machine learning is a type of data analysis that automates the creation of analytical models. It’s a field of artificial intelligence based on the premise that computers can learn from data, recognise patterns, and make judgments with little or no human input.

Pattern recognition

Pattern recognition technology is a type of technology that recognises patterns in data (often used interchangeably with machine learning). The process of recognising patterns using a machine learning algorithm is known as pattern recognition. The classification of data based on prior knowledge or statistical information taken from patterns and/or their representation is known as pattern recognition. Pattern recognition’s application potential is one of its most essential features.

Examples: Speech recognition, speaker identification, multimedia document recognition (MDR), automatic medical diagnosis.

Data preparation

the process of turning raw data into a format that can be absorbed more easily. The process of cleaning and altering raw data prior to processing and analysis is known as data preparation. It’s a crucial stage before processing that often include reformatting data, making data changes, and integrating data sets to enrich data.

Text analytics:

The process of analyzing unstructured data in order to get important business insights. Text analytics is the act of automatically converting vast amounts of unstructured text into numerical data in order to identify insights, trends, and patterns. This methodology, when combined with data visualization tools, allows businesses to comprehend the story behind the numbers and make better decisions.

How can you become a data scientist?

Preparing for a job in data science could be a wise decision. You’ll have plenty of job opportunities, as well as the opportunity to work in the technological industry, where you may explore and be creative. So, what’s your plan?

If you’re a student:

The first step is to find a university that offers a data science degree — or at the very least, classes in data science and analytics. Universities providing data science programmes include Oklahoma State University, University of Alabama, Kennesaw State University, Southern Methodist University, North Carolina State University, and Texas A&M.

If you’re a professional who wants to shift careers

While the majority of data scientists have worked as data analysts or statisticians, others have backgrounds in non-technical domains such as business or economics. How do people with such disparate backgrounds wind up working in the same field? It’s crucial to consider what they all have in common: a flair for problem-solving, excellent communication skills, and an intense curiosity about how things work.

Aside from those qualities, you’ll need a firm grasp on the following:

  • Statistics and machine learning.
  • Coding languages such as SAS, R or Python.
  • Databases such as MySQL and Postgres.
  • Data visualization and reporting technologies.
  • Hadoop and MapReduce.

When is a business ready to hire a data scientist?

Before you accept a data scientist position, you should look at the following aspects of the company:

Does it deal with large amounts of data and have complex issues that need to be solved?

Organizations that actually require data scientists have two things in common: they handle large volumes of data and deal with complex problems on a daily basis. They’re usually found in industries like finance, government, and pharmaceuticals.

Does it value data?

The culture of a firm influences whether or not it should hire a data scientist. Does it have an analytics-friendly environment? Is it backed by the board of directors? Otherwise, hiring a data scientist would be a waste of money.

Is it ready to change?

As a data scientist, you expect to be taken seriously, and seeing your work come to fruition is part of that. You devote your time to figuring out how to make your company run more smoothly. As a result, a company must be prepared – and willing – to implement the conclusions of your investigation.

For some businesses, hiring a data scientist to steer data-driven business choices is a risky move. Check to see if the company you’re considering working for has the correct mindset – and is willing to change.
