Complete Roadmap to Make a Career in The Data Science Field
Today in this article we will discuss what is Data Science and also discuss the complete road map to follow step by step to make a career in the field of Data Science. So, let’s start.
First of all, let’s talk about Data Science. We have heard about Machine Learning and Artificial Intelligence in recent years. We have recently seen the Chad GPT. All these things are possible because of data science.
What is Data Science:
To understand data science, we take the example of online entertainment platforms.
If you use a service like Netflix or Prime Video and watch a lot of horror movies on it, then what will Netflix do? If a new horror movie has come, it will suggest it to you. So what did they do? They use your patterns, that is, what kind of content you watch, and what kind of TV shows and movies you watch. Shows movies, content media platforms, and shopping platforms like Amazon, all these platforms want to keep users on them for a long time and use them as much as possible.
That is why they want to find some common patterns based on user activity, based on which they can keep users engaged on their platform. This is an example of a solution using data science.
The job of a Data Scientist:
Data science is a mix of Math Statistics, Programming, Data, and Machine Learning. Many things are a mixture of data science. In data science, we have machine learning jobs, data analyst jobs, and big data-based jobs. Now we know that there are many big companies and they have a lot of data. So we don’t call a big company’s data just data, we call it big data. Because companies have a lot of data today.
Now the job of a data scientist is to collect this data, then analyze it, then process it, and finally get some useful insights from this data. Useful insights mean getting useful information, such as information that can be useful for their company, which can help their users in a better way or grow their platform more. So, in this way, when we mix business skills with algorithms, data skills, and math, we get a field of data science. Now, to become a data scientist, we have to perform many steps in the Data Science field. To become a Data Scientist, we have to perform many steps to learn the skills.
Now, in the field of Data Science, it is not necessary that we have to study Math. Anyone can come and if they invest good time in data science, they can learn these skills and make a good career.
Let us talk about the steps by which we can make a career in the field of Data Science.
Step 1 Learn a Programming Language:
Generally, there are two major programming languages in data science. One is Python and the other is R. Python is the most popular among them. Why? Because it has very good libraries and resources. So first of all, you have to learn the basics of Python, in the basics of Python you learn variables, if else, and loops so you have to learn basic things in Python, and after that, you have to learn two libraries in Python, one is numpy and other is pandas these libraries help you to deal with data and how you can interact with Data.
Step 2 Learn some Statistics:
It is important to understand all the things that come under Data Science because if we look at this chart then according to professionals in recent years most of the jobs in the Data Science field are in Data Analytics and Data Analytics generally we are more from the business side. Let’s deal with it. Or the analytics side, in which our concepts about statistics should indeed be strong but we can still get by if we have not studied much mathematics or we have not gone very deep.
Step 3 Learn Matrices:
Now in math, there are four major topics In statistics, you have to understand things like mean, median, mode, variance, and standard deviation. Not only to keep things but to understand how all these things relate to data. And if you calculate the mean in the data, then what is the actual meaning of that mean? In linear algebra, you will study topics like vectors, matrices, and eigenvalues.
The third thing you have to study is calculus. What are the derivatives in calculus? What is the actual meaning of the term dy by dx in math? You have to learn all these things. The fourth thing you have to learn is probability. What are odds, conditions, and probabilities? Bayes theorem which is very important? How to use all these practically. You have to learn this. So from here your basics of math i.e. statistics, probability, calculus, linear algebra, etc. will be covered. You have to study these properly.
Step 4 Learn Data Visualization:
Visualization is important because when you work with businesses, you become data scientists but how can other people understand the insights and patterns you have found in your data? They will be able to understand it using graphs and charts. To make such things, you have to learn data visualization. To learn this, you will cover two very famous libraries in Python. One is Matplotlib and the other is Seaborn. and So, let’s assume that in data visualization, you have to learn more advanced things. So, you can learn more good tools in that, like Power BI, like Tableau. But if you are a fresher, then you can ignore both the tools in the college. Anyway, if you go to the job of a data analyst, then you will be learning on the job.
Step 5 Learn Machine Learning:
That is, actually applying machine learning algorithms to data. In ML algorithms, we have four major types of algorithms, first one is supervised, second is unsupervised, third is semi-supervised, and the fourth is reinforcement learning. We can learn different types of algorithms in these algorithms. And then we can apply those algorithms to data.
Now how to learn machine learning, where to start, what kind of process will be there, and what resources will be there, Digiperform has a dedicated online course on that. You can join our Digiperform Online Data Science Course. Now whenever you apply ML algorithms to data, it is very important to a project field, you can directly create your own GitHub account. And you can host all the projects you create there.
So our basic 5 step roadmap was to go into the field of data science. Now let’s assume you have learned all these things. So after that, you will have a choice that you can specialize in any of these. Let’s assume that there are many different parts in the field of data science. into the side that you already have a master’s or PhD.
So if you want to go into the field of data science, especially in algorithms or big data, then if you have an actual interest in that, you can consider that over the years you will be taking a master’s degree in that field. Otherwise, as a fresher, you have data analyst opportunities available to which you can apply. And you can also establish a good career in them.
So we hope that in this article you have got some clarity that if you want to make a career in the data science field then what steps you have to take, which resources you have to follow, and what things you can take care of over the years if you are going in this field.
