How to become a data scientist

A data scientist may be a professional referred to as the sexiest job of the 21st century. Also, research conducted by McKinsey Global Institute back in 2013 projected that there’ll be approximately 425,000 and 475,000 unfilled data analytics’ positions in North America by 2018. The take-home message here is that there’ll be a continuing stream of analytic talent that is going to be required altogether industries, where companies collect and use data for his or her competitive advantages. Many think about how to become a data scientist what is the scope of data science and many other things.

What exactly a data scientist?

In an oversimplified description, a data scientist may be a professional who can work with an outsized amount of data and extract analytical insights. they convey their findings to the stakeholders (i.e., senior leadership, management, and clients). Thus, companies can enjoy making the best-informed decisions to drive their business growth and profitability (i.e., depends on the context of industries). let’s move further and see how to become a data scientist.

 

Why is it so hard to become a data scientist and How to become a data scientist?

The nature of knowledge science may be a hybrid of many disciplines. Where it composed of various subject areas like math (i.e., statistics, calculus, etc.), management, data visualization, programming/software engineering, domain knowledge, etc. In my opinion, this might be the first reason why people curious about jumping into the entry-level data science career often feel completely lost. most of the people don’t know where to start out because you’ll lack in one area completely or multiple areas depend upon one’s educational background and work experience.
However, the great news is that you simply don’t get to worry an excessive amount of about it. lately, we face the completely opposite side of a problem. There are just too many resources out there to select. So, you don’t necessarily know which one might compute best for you. during this article, I will be able to be focused on the way to become a knowledge scientist from three perspectives. Let’s do deep dive and solve your problem of How to become a data scientist.

Section 1: Where to find out data science?

this is the first step to answer your question How to become a data scientist?
Let’s start from where to find out data science. There are three major pathways to get data science education from Massive Open Online Courses (MOOC), university degree/certificate, and camp training.
Here may be a sample figure which demonstrates the estimated time commitment vs. job placement success rate in each option. This provides a thought that the camp education can offer you a foothold on landing a knowledge scientist job quicker than the opposite two options.

Section 2: What to find out data science?

1 3LJNeploSYM UAolf4nT Q How to become a data scientist?

this is the second step to answer your question How to become a data scientist? and it has several steps further to become a data scientist.

There are many things to find out needless to say as a knowledge scientist. Let’s start watching the data science education pathway from five major steps.

Step 1, catching abreast of the essential math associated with statistics, calculus, and algebra may be a good start. this is often essential as a knowledge scientist to know the mechanisms behind how different algorithms work. It builds intuition about the way to tweak or modify algorithms for solving unique business problems. Also, knowing the statistics helps you to convert your findings from the experimental design tests (i.e., A/B testing) into key business metrics. this is the first stage where you will grow skills and solve the query of how to become a data scientist specialist.

Step 2, data scientists must be conversant in a toolset to figure with data in various environments. A toolset contains a mixture of SQL, instruction, coding, and cloud tool. Here may be a summary of how each tool is employed. For data extraction and manipulation from the relational databases, SQL is that the fundamental language utilized in almost anywhere. For general programming purposes (i.e., functions, for loops, iterations, etc.), Python may be a good selection since it already packaged with many libraries (i.e., visualization, machine learning, etc.). For a further boost, knowing command lines provide extra benefits especially for running jobs within cloud environments. this is the second stage where you will grow skills and solve the query of how to become a data scientist specialist.

Step 3, this is often the simplest time to select up some language for building the info science foundation. For commercial software, you’ve got a choice between SAS or SPSS. From open-source platforms, many of us choose either R or Python. From here, you’ll grab concepts about data munging/wrangling (i.e., import data, aggregation, pivoting data, and missing value treatment). After this, you’ve got the foremost fun a part of learning your data from data visualization (i.e., bar charts, histograms, pie charts, heat maps, and map visualizations). this is the third stage where you will grow skills and solve the query of how to become a data scientist specialist.

Step 4, you’ve got an option to pick between applied machine learning or big data ecosystem pathway. Note that you simply can always come to master another path later. In my case, I select to find out about the applied machine learning first. Basically, it covers the aspect of building a machine learning model from an end to finish (i.e., data exploration to model deployment). For learning about the large data, I will be able to cover more about where to get that education (i.e., books and courses). this is the fourth stage where you will grow skills and solve the query of how to become a data scientist specialist.

Step 5, this is often the foremost crucial step to showcase your potential as a knowledge scientist candidate. Once you familiarize yourself with doing the info science, one must have a project portfolio. A project portfolio is your best opportunity to point out what you’ve got done from learning and work experiences. ranging from the info collection (i.e., where to select or scrape data on your own), come up together with your hypothesis, perform exploratory analysis (i.e., extract some interesting insights), build your machine learning model(s) and eventually share your findings from write up or presentations. In my case, I even have done both a write-up and a video podcast by performing on the capstone project with an assigned mentor. I can never emphasize enough about the importance of getting a mentor who can directly work with you 1 on 1. Your mentor is that the ally to guide you and invite help once you grind to a halt on some project ideas, tuning your model, communicating your results, etc. In fact, some researches mentioned that having a mentor can boost your career five times quite people without a mentor(s). this is the fifth stage where you will grow skills and solve the query of how to become a data scientist specialist.

Section 3: the way to learn data science?

this is the third step to answer your question How to become a data scientist?

In this section, you’re getting to find out how to select the simplest resources for becoming a knowledge scientist. I would like to form recommendations that supported my learning experience.

For SQL education, the DAT201x course offered by Microsoft from the Edx is one of the simplest choices. The course covers the subsequent aspects of SQL from data types, filtering, joins, aggregation (group by), window functions, and advanced concepts (i.e., stored procedures). The course ensures you to practice tons by using the simplest sample data warehouse (i.e., AdventureWorks). Alternatively, you’ll use the Mode Analytics platform to practice and enhance your SQL skills. the simplest thing about Mode Analytics is you don’t get to have a SQL server and sample data warehouse installed in your machine. All you would like is to possess a free account and Internet connection to enjoy your learning.
For machine learning education, there are two options that I prefer to recommend. the primary course is well-known from any data science practitioners out there within the field. Andrew Ng’s machine learning course from Coursera. I used this course to know basic concepts and recommendations on the way to tune my machine learning models. For the coding experience perspective, I might highly recommend this book called Python Machine Learning 2nd edition by Sebastian Raschka. I actually think this is often the simplest machine learning book. This book helps you understand from basic mechanisms of every algorithm, tons of coding examples, and supplemental references (i.e., research articles). the simplest thing about this book is that he walkthroughs the way to implement each machine learning algorithm line by line with thorough explanations. this is often super important as mentioned by many data scientists, one should be ready to write up coding from scratch and skills to implement it. lately, there are many complex problems that you simply cannot solve directly by using existing libraries from Python.
Here may be a full list of resources you’ll reference for learning each building block of the info science education.

1. Math:
