“how similar or different these roles are”, “what technologies each of
the roles require”, and “what responsibilities they entail”.
Industry Verticals Employing Data Science
• Before Data Science was popularly known amongst industry verticals,
most companies weren’t aware of new age Data Science tools. They
didn’t know how to analyze and explore the collected data. Despite
the thorough collection of broad sales figures and customer
information, drilling down the data and drawing insights from it was
time-consuming. This required the expertise of a niche Data Scientist.

12.
• The growth in popularity of Data Science and Analytical tools has
changed the perspective of how industries operate. Data Scientists
are armed with high-end analytical tools which allow them to create
powerful visualizations from company data and use it to benefit the
organization.

• Important Topics In Data Science
• The continuing importance of Data Science is not a fact to be ignored.
One thing is clear that the field is here to stay. However, what a Data
Scientist does will evolve. With technologies like Machine Learning
becoming ever-more commonplace and emerging fields like Deep
Learning gaining significant traction amongst researchers and
engineers — and the companies that hire them — Data Scientists
continue to ride the crest of an incredible wave of innovation and
technological progress.
Data Scientists work in a space which is at the juncture of coding,
statistics, and critical thinking. Josh Wills says, “A Data Scientist is a
person who is better at statistics than any programmer and better at
programming than any statistician.” Any comprehensive data science
course will cover:

16.
• Python and R
• Python and R are the two most popular programming
languages. Data Analysts and Data Scientists mostly use these
languages. Both are open source and free. R is used for statistical
analysis and Python is used as a general-purpose programming
language. Therefore, for anyone looking to study in Machine Learning,
or working with large datasets, or creating complex data
visualizations, knowledge of Python and R is an important
prerequisite.
• Statistics
• Statistics studies methodologies to gather, review, analyze and draw
conclusions from data. Some of the statistical concepts useful for data
scientists are mean, regression analysis, skewness, kurtosis, variance,
and analysis of variance. The two main statistical methods that data
scientists use for analysis are descriptive statistics and

17.
• inferential statistics.

It is about “Why is Statistics a Necessary Skill for Every Data Scientist?”.
• Artificial Intelligence (AI)
• AI infuses intelligence into machines. It uses Computer Apparition (to help
machines understand the world around them), and Language Dispensation
(speech and text processing) to help machines understand human text and
speech so that they can respond to them naturally.
• Machine Learning
• Machine Learning is a method of data analysis that automates analytical
model building. It is a branch of Artificial Intelligence, which is built on the
idea that machines can learn and adapt to experience. Data Mining, Data
Engineering, Data Science all use statistical learning algorithms (Machine
Learning) to gather intelligence from the data.

18.
• Future Of Data Science And Data Scientists
• The future of Data Science is all about predictive models — lots of models
running in a semi-automated manner at the truly enormous measure.
Descriptive analysis is the history of Data Science, which explains what has
already taken place. Conversely, the future of Data Science will center on
advanced analytics — which uses predictive analytics and real-time
analytics in pursuit of business goals, such as refining products and
services, and reducing cost and churn rate.
The tools and technologies that modern Data Scientists employ are a
combination of statistical and Machine Learning algorithms. They are used
to discover patterns using predictive models. The future of Data Science is
bright and the options for its implementation are extensive.
Data Scientists must consistently evolve and be at the edge of innovation
and creativity. They must be aware of the types of models they create.
These innovations will allow them to spend time discovering new things
that may be of value. Subsequently, the advances in Data Science tools will
help leverage existing Data Science talent to a greater extent.
