Moreover, for beginners, it is the key to having an aspiring excellent career.

Before knowing about the ways to learn data science, let’s have a brief about the basics of it.

Data Science Overview

Data Science has shown rapid growth in the past few years. Many new startups are focusing their businesses using data science technologies. Talking about jobs, the number of data science jobs have also increased in the past few years. And, these numbers are growing at a constant rate as well as are the number of positions. As a result, top companies have shifted their base from traditional software development and are adopting Data Science.

But, one question arises here that is, why is it in demand? Let’s put some light and understand the need for it.

Is Data Science in demand?

There are a few points that will help to know about the importance of data science.

  • Firstly, the supply for Data Scientist is intensely rare, but the demand is large. And, this supply-demand gap is limiting its size as there are many data scientists who are entering the job market.
  • Secondly, the Data Science professionals have knowledge of at least one programming language as well as experience in tools like Hadoop, Spark, NoSQL. Not to mention, all these skills are usually hard to find in one person.
  • Due to its high demand, the salaries for the position have also increased. And certainly, this job is among the highest-paying in the industry right now.

Data Scientist: Knowledge Requirement

In the Data Science field, you must have the required skills to dive into the world of data. However, it doesn’t matter whether you are an expert or not because the data scientist is available for all. Below we will see the different areas where data science is applicable and what knowledge you should have. So, let’s begin with BI.

  • Business Intelligence

There is a big similarity between Data Science and Business Intelligence as they both focus on data to provide outcomes and offer reliable decision-support systems. The BI works with static and structured data whereas Data Science handles complex and multi-structured data from data sources. Moreover, BI helps illuminate the past data for reporting and Data Science analyzes past data to make future predictions in predictive analytics or prescriptive analytics.

  • Statistics and probability

Probability and statistics refer to the basics of Data Science. Where Statistics means using mathematics to perform technical analysis of data. And, using statistical methods, the estimates for further analysis. Statistical methods are mostly dependent on the theory of probability, to make predictions. However, as a beginner data scientist, you can start with basic statistics concepts that include,

  • Machine Learning and AI

This area is quite complex and requires high-level knowledge as a large number of data scientists are not proficient in Machine Learning areas and AI techniques. However, in Data Science you have to work on large amounts of data sets that require knowledge of machine learning techniques.

Whereas, at the entry-level, Machine Learning does not require much knowledge of math or programming, just interest, and motivation. The ML has three main categories of algorithms that include:

Programming Language you must know to become a Data Science Pro!

Data Science is a good field to work in, as it will advance your statistical and quantitative skills with real-world programming. Moreover, you can choose a programming language according to your background. Not to mention, the most popular ones are,

R Programming

R is a powerful language designed for Data Scientists. Moreover, it stands out a huge variety of statistical and data visualization applications. And, R is considered as a magnificent tool for solving complex statistical problems. However, to turn into a proficient Data Scientist, it is necessary that you learn R.

Python

Python refers to a common language in Data Science. Because of an all-rounder, Python can be used in almost all steps of data analysis. Moreover, it allows you to create datasets and is perfect for entry-level and easy-to-learn.

SQL

SQL is considered as a data processing language rather than as an advanced analytical tool. And, it helps you to perform operations like add, delete and extract data from a database and transforming database structures. Even though NoSQL and Hadoop have become a large component of Data Science, still data scientists can write and execute complex queries in SQL.

Advanced Microsoft Excel

Excel is a perfect tool for Data Science and is generally utilized for data analysis, making spreadsheets, perception and complex calculations. Moreover, you can actualize the essential ideas of Statistics in Excel.

Based on the above skill there are levels of certification that are available to become data scientists.

Top Certifications For Data Scientist

Things to Consider as a Data Scientist

There are several things to take into consideration in Data Science.

  • Analytical Mindset: This is a common requirement for any person working with data. However, it is required to have a statistical background and good knowledge of data structures and machine learning algorithms.
  • Focus on Problem Solving: The goal of Data Science is to solve problems by extracting the knowledge from data. And, a data scientist first understands the problem after that it defines the requirements for the solution to the problem.
  • Domain Knowledge: Data scientists need to understand the business problem and then, choose appropriate models for the problem. Moreover, they should be able to understand the results of their models.
  • Communication Skills: Data scientists should be able to clearly document their approach so that anyone can easily understand research work published in their area.
