Data Science Courses

Data Science is the art of presenting large volumes of data in a simple and easy-to-understand format that enables you to extract useful information and draw inferences. In the new age, businesses heavily rely on data, and given the manner in which data is driving and transforming businesses, it becomes more important to evaluate and handle the data scientifically. This is why DS is gaining popularity nowadays. As its importance grows with each passing day, there are a number of new growth opportunities in this field as well. This is why learning data science to build a career is a good choice.

It involves scientific methods and statistical techniques to derive relevant information from the data. The information extracted from large data sets in turn helps to make important business decisions, understand customer needs, and compute market demand. There are many fields in which there is a dire need for data scientists, statisticians, architects, and analysts. The demand for data professionals is expected to increase in the coming years as there will be more integration and implementation of data science applications like Machine Learning, Artificial Intelligence, and Deep Learning, etc. The relevant knowledge and required skill set can be easily acquired with a comprehensive data science course



Overview of the Data Science Online Course 

The Data Science course curriculum includes instruction in a variety of subjects such as mathematics, statistics, programming, data visualization, and so on. Let us look into each of these in detail.


The DS models and tools mostly work with simple mathematical formulas. It is thus necessary to learn mathematics to work efficiently in the field of data science.


Knowledge of programming languages is a must for data scientists. They must be well versed in coding algorithms and work with databases. The data science curriculum thus emphasises laying a strong foundation in programming languages such as Java, Python, C, and C++ and their usage in business.

Data Visualization

It is one of the most important topics included in the DS curriculum as it helps learners understand the ways of representing data in a graphical form, including pie charts, diagrams, and images, to present reports on analytical concepts.

Machine Learning

It is a part of data science that helps make machines intelligent and smart. This enables machines to perform functions similar to those of the human brain. It includes the study of technology, machine learning systems, and other modern technologies.

Probability and Statistics

Probability and Statistics techniques help to perform data segregation with ease.

Data Science Process

Data science is applied to data and aids in the extraction of information by following a process. The five important stages of data processing are:

Collect: The first step in the process is data acquisition and extraction. It includes data entry, signal reception, and gathering raw, structured, as well as unstructured data.

Manage: This step involves Data Cleansing, Processing, Warehousing and Architecting. It involves taking raw data and putting it in a systematic form.

Process: Processing data includes methods such as mining, modelling, classifying, and summarizing. The scientists take prepared data and study the range, patterns, categories, etc. before determining its usage in predictive analytics.

Analyze: The data is analysed using various exploratory, confirmatory, predictive, regressive, and qualitative methods. This is the principal step of the data processing cycle.

Report: The final step of data processing is finalising the report that is created to facilitate the extraction of information required for business decision-making. The reports are usually prepared in an easy-to-read format with the use of charts, graphs, and diagrams.


Who are data scientists?

Individuals who are experts in data management flow are known as "data scientists." They collect, manage, analyse, process, and interpret data to draw inferences.

Data analysts must possess some key skills, such as mathematical & statistical skills, programming skills, and data visualisation & wrangling.

Data Scientist

A Data Scientist is responsible for finding answers to complex questions through data processing. They are responsible for extracting, cleansing, and preparing the significant data. They require skills like storytelling, data visualization, statistics, mathematical ability, programming skills, Hadoop, SQL, and Machine Learning.

Data Engineer

Data Engineers are responsible for organizing, developing, managing, deploying, and optimising organisational data. The data engineers help the data scientists with transferring and transforming data for handling queries. Data Engineers must have an understanding of databases, different frameworks, and programming languages.


Data Science Expert-Skills

A data science expert should be proficient in data handling, which calls for a set of skills that they must possess to handle data effectively. The eligibility criteria for the data science certification course is that the aspirants must be graduates from any stream who have secured an aggregate score of 50% or more. It is widely assumed that individuals with backgrounds in engineering, information technology, marketing, and other related fields are well-suited for data science positions. It can also be pursued by working professionals who have completed their BBA or MBA.


What are the tools used by Data Experts?

There are various tools useful for Data professionals required to combat the challenges faced by them in handling the data, few of them are R Studio, SAS, RapidMiner, AWS Redshift, Excel, MATLAB, Jupyter, Informatica, Tableau, RAW, Cognos, SPARK, Azure ML, etc.
