What Is Data Science?
Technically speaking, Data science is the study that deals with vast volumes of data with the help of modern & sophisticated tools and techniques to figure out the unseen patterns, derive meaningful information, and take profitable business decisions. Data Science uses complex machine learning algorithms that help you to build a predictive model. The data used for analysis is fetched through multiple sources and present in various formats.
Now that you got an idea of what is data science, let’s see why data science is so important in the current market scenario. 

Why Data Science?
Data science helps companies take better decisions, do predictive analysis, and pattern discovery. It lets you:

  • Identify the leading cause of a problem by triggering the right questions

  • Perform exploratory study on the data

  • Model the data using various algorithms 

  • Communicate and visualize the results via graphs, dashboards, etc.

For instance, if you consider an airline industry, here is how you can optimize operations in many ways such as:

  • Line-up routes and decide whether to schedule direct or connecting flights

  • Build predictive analytics models to forecast flight delays based on climates, jetlags, or global events

  • Give personalized promotional offers based on the customers booking & ratings

  • Decide which planes to buy for fuel efficiency and better performance

In a layman’s term, let’s say you want to buy new sneakers. So, when you look online for the best option and deal, you need to answer some critical questions before making your decision such as:
Does the site sell sneakers

  • What is the range you’re looking for?

  • What is the size you’re looking for?

  • What colours you’re finding?

  • Is there any festive or seasonal discount?

  • Is there any promotional coupon code?

It will help companies apply advanced filters that will perfectly match your needs and give a smooth customer purchase experience.

Things To Know Before You Learn Data Science
Here are some of the technical concepts you should know before you study Data Science:
Machine Learning
It’s the backbone of data science and as a data scientist, you need to have a good grasp of the ML concepts along with the basic knowledge of statistics. 
Mathematical models will help you make quick calculations and predictions on things you know about the vast data. Modelling also comes under Machine learning and involves identifying which algorithm is the most suitable to solve a given problem and how to train these models.
Statistical Knowledge
Statistics are at the core of data science. A good grasp of statistics will help you extract more intelligence and obtain better meaningful results.
Programming Languages
A certain level of programming language is also required to complete your data science project. One of the common languages would be Python and R. Python is quite popular because it’s easy to learn, and it supports multiple libraries for data science and ML. Find out a data science course for you with Python – Clickhere

What Does A Data Scientist Do?
In the last couple of years, data scientist has been an integral part of any organization and its marketing strategy. It has become a necessary asset and is present in every form of business, sector, or industry. These professionals are brilliant minds, data-driven with hi-end technical skills who are capable of creating quantitative algorithms to organize and synthesize large amounts of information. It's then coupled with the communication and leadership needed to deliver tangible results to various stakeholders across an organization or business.
Data Scientists are curious and result-oriented individuals with excellent industry-relevant knowledge and communication skills to explain highly technical charts, statistics, and forecasts for any business or venture. They possess a strong quantitative background in statistics and linear algebra, sound programming knowledge with focuses on data warehousing, mining, and modeling to build and analyse algorithms.

As A Data Scientist  you will:

  • Ask the right questions to understand the problem

  • Gather data from multiple sources—enterprise data, public domain, etc

  • Process raw data and convert it into a format suitable for analysis

  • Feed the data into the analytic systems —ML algorithm or a statistical model

  • Prepare the results & insights to share with the appropriate stakeholders

Therefore, you should be aware of some machine learning algorithms which are beneficial in understanding data science.
Other than this, some key technical tools and skills you need to be savvy with include: R, Python, Apache Hadoop, MapReduce, Apache Spark, NoSQL databases, Cloud computing, D3, Apache Pig, Tableau, iPython notebook, and GitHub.

Must Knowledge Of Machine Learning Algorithms
The most basic and essential ML algorithms that data scientist uses include: 
Regression - It’s an ML algorithm based on supervised learning techniques. The output of regression is a real or continuous value. For example, predicting the temperature of a room.
Clustering - It’s an ML algorithm based on unsupervised learning techniques. It works on a set of unlabelled data points and groups each data point into a cluster.
Decision Tree - It refers to a supervised learning method used primarily for classification. The algorithm classifies the various inputs according to a specific parameter. The most significant advantage of a decision tree is that it is easy to understand, and it clearly shows the reason for its classification.
Support Vector Machines (SVMs) - It is also a supervised learning method used primarily for classification. SVMs can perform both linear and non-linear classifications.
Naive Bayes - It is a statistical probability-based classification method best used for binary and multi-class classification problems.
