A data scientist is what?

A professional with expertise in data analysis and interpretation is known as a data scientist. They help organisations make better decisions and run more efficiently by utilising their data science skills. Data scientists frequently come from backgrounds in computer science, statistics, and mathematics. They analyse sizable data sets using this knowledge to look for trends or patterns. Data scientists might also create brand-new techniques for gathering and storing data.

Why Work as a Data Scientist ?

One might decide to pursue a career in data science for a variety of reasons. The industry offers a stimulating and intellectually challenging environment, which has the potential to be very rewarding. Working in an environment that is frequently dynamic, data scientists must stay on top of the most recent technological trends and advancements.

So, if you enjoy working with data and technology and have an analytical mind, becoming a data scientist may be for you.

Talented data scientists also have a lot of job opportunities available to them. Big data market size is anticipated to increase significantly over the next few years, according to statista data, from $70 billion in 2022 to $103 billion in 2027.

Requirements and Eligibility to become Data Scientist

You must have excellent analytical and mathematical skills if you want to become a data scientist. You should be able to comprehend and deal with complex data sets. You should also be able to use statistical software programmes and be familiar with programming languages like Python or R. Additionally, most data scientists hold a certification from a recognised programme.

What Knowledge Are Required for Data Scientists?

Here, we’ll provide a summary of the top 15 data scientist skills, which were covered in greater detail in a separate article. In essence, a mix of hard and soft skills are required to succeed in data science.

A Hard Skills

The technical abilities you must acquire to become a fully qualified data scientist are as follows:



Mathematics and Statistics


Visualizing data

Automated learning

Advanced learning

Processing natural language

‘Big Data’

Using the cloud

A soft skill

These cross-functional skills, which are not job-specific but are still important, are now more commonly referred to as “power skills” or “human skills.” These consist of, for a data scientist:

  • Communication
  • Storytelling
  • Critical reasoning
  • business sense
  • Problem-solving
  • Teamwork

7 Skills to Become A Data Scientist

You must become an expert in the following areas if you want to work as a data scientist:

Skill 1: Learn about databases, which are necessary to store and analyse data using programmes like Teradata®, Microsoft® SQL Server, Oracle® Database, and MySQL®.


Skill 2: Study probability, statistics, and mathematical analysis. The science of statistics focuses on creating and researching strategies for gathering, analysing, interpreting, and presenting empirical data. Probability is a way to gauge how likely something is to happen.

Skill 3: The area of mathematics known as mathematical analysis is concerned with limits and theories that are connected to them, including measure, infinite series, differentiation, integration, and analytic functions. At least one programming language should be mastered. When performing analytics on data, programming languages like R, Python, and SAS are crucial.

Skill 4: Most Machine Learning algorithms for Data Analytics, including regression, association, and clustering, are supported by R, a free software environment for statistical computing and graphics.
A general-purpose programming language that is open-source is called Python. Data science uses Python libraries like SciPy and NumPy.
Statistical analysis can be done on the data using SAS, which can also mine, modify, manage, and retrieve data from a variety of sources.

Skill 5: Learn how to organise, manipulate, and clean up data by practising data wrangling. R, Python, Flume, and Scoop are well-liked data wrangling tools.

Skill 6: Become an expert in machine learning concepts. Giving systems the capacity to automatically learn from experience and get better without being specifically programmed to. Different algorithms, including Regressions, Naive Bayes, SVM, K Means Clustering, KNN, and Decision Tree algorithms, to name a few, can be used to achieve machine learning.

Skill 7: Utilising Big Data tools, such as Apache Spark, Hadoop, Talend, and Tableau, to handle large and complex data sets that cannot be handled by conventional data processing software.
