What Is a Data Scientist?

A technological specialist who specializes in data collection, management, manipulation, and analysis is known as a data scientist. 

What Does a Data Scientist Do?

Data scientists comprehend the data, and then use it to exhibit or forecast useful and profitable insights. 
Data scientists spend a lot of their time obtaining and preparing data since they frequently work with enormously massive data sets, or big data, as it is commonly referred to. 
A data scientist evaluates this data to derive useful business insights, feed it to an AI or machine learning project, build and write new software to simplify the data wrangling process, and arrange it in a database, depending on the particulars of the function.

How To Become A Data Scientist - 7 Steps

1. Brush Up on Data Science Fundamentals

Starting out small is never a waste of time because it allows you to focus on the basics before moving on to specialized areas of interest. Your energy should be directed at the following:
  • Statistical Analysis: This refers to the analysis of data and the correct and unbiased presentation of the results using statistics. 
  • Programming: Key competencies used in many areas of data science include writing code and creating software. 
  • Data Visualization: Data is presented in tables, graphs, charts, and dashboards so that both technical and non-technical people can quickly and easily understand it. 
  • Machine Learning: Creating software that learns from the information provided to it and uses that information to nimbly alter its operations in response to various circumstances. 

2. Meet the Educational Requirements

Although a college degree is not necessary to become a data scientist, there are some educational prerequisites you need to be aware of. For Example, you should have a mathematics background with good scores in math, you should be well aware of statistics, and you should be familiar with basic computer operations. 
Take a Certified Course from InsideAIML
There are various entry points into the data science community if you don't have or don't intend to obtain a college degree. You can obtain a thorough, practical education in the field of data science by taking a certified course from InsideAIML.

3. Hone Essential Skills

Technical Skills

  • Programming Languages: A data scientist should be proficient in Python and generally knowledgeable in one or two other languages, such as R or SQL. 
  • Data Mining: Data mining is the process of acquiring pertinent and reliable information from various sectors, as well as frequently from outside sources. 
  • Data Visualization: A crucial talent for data scientists is the ability to use data visualization tools like Tableau, Microsoft Excel, and Google Charts to display data in an understandable manner. 
  • Data Analysis: This is the process of searching through and examining structured data to look for trends and interesting areas that can be turned into useful information and commercial prospects.
  • Statistics: When establishing company plans, statistics help decision-makers differentiate fact from fiction by offering unbiased views based solely on numbers and data.   
  • Machine Learning: After studying the basic theories underlying machine learning, you might wish to specialize in it, which would require continuing your education and working on your own machine learning tasks. 
  • Deep Learning: Machine learning's deep learning subfield aims to create artificial neural networks that mimic how people learn specific types of information.  
  • Natural Language Processing: Natural language processing (NLP), a subfield of machine learning, is a key component of virtual assistants like Apple's Siri and Amazon's Alexa.
  • Algorithms: Algorithms are collections of rules that carry out calculations and solve issues. AI can be used to train them to make automatic decisions. 
  • Data Engineering: Data gathering, wrangling, cleaning, and other preparatory processes are all considered to be data engineering abilities.

Soft Skills

  • Analytical Mindset: Data science requires an analytical mentality since it involves more than just deriving the right conclusions from data sets. It also involves formulating the right questions to ask. 
  • Business Acumen: Many data scientists strive to make their employers' businesses better, whether it means increasing productivity, boosting earnings, developing valuable ideas, or discovering innovative methods to cut costs. Data scientists need to comprehend what a business requires in addition to being able to read the data. 
  • Critical Thinking: Critical thinking is especially helpful during the data cleaning and wrangling process since it helps identify abnormalities and inaccurate values with collections of data.
  • Adaptability and Flexibility: Data may not always provide us with the information we need since it is what it is, not what we wish it to be. Adaptability and flexibility are essential for getting beyond difficulties and using them to your advantage. 
  • Collaboration and Teamwork: Data scientists typically work in teams, therefore they must get along well with one another. In order to gather data and communicate their findings, they must also work in conjunction with other departments. 
  • Problem-Solving: You'll be a valuable member of any team if you put effort into finding solutions and developing your problem-solving abilities.
