The tech industry is marked by continuous ups and downs. Amidst this upheaval, the significance of Data analytics in defining career opportunities is undebatable. Job roles surrounding Data Management are selling like hot cakes.

Even among these roles, there are some which are considered to be slightly more coveted in terms of their demand, career prospects and the remuneration they attract. One such role is that of a Data Scientist.

Consequently, it is important to understand the transition route which one might opt for from different positions like that of a Data Analyst to Data Scientist, from a Business Analyst to Data Scientist and so on.

In this blog, we shall try and answer the question of how to go from Data Analyst to Data Scientist.

Before seeking to understand the transition from Data Analysts to Data Scientists, we shall take a synoptic view of the difference between the two career positions. Additionally, we shall look at the career transition from Business Analyst to Data Scientist.

Data Analyst vs. Data Scientist 

Before delving into the question of how to move from Data Analyst to Data Scientist, it is important to understand the difference between the two career positions. This is especially because there is considerable overlap between the different job roles as they happen to be concerned with Data in difference ways.

Firstly, a Data Scientist happens to possess skills which are considered to be more advanced than that of a Data Analyst. Let us try to understand the two positions in this way: a business firm makes and sells baby cardigans.

It was consequently noticed that parents who came to buy the cardigans, often enquired about matching booties for their little ones. When you share this finding with the marketing team of the firm, you are largely working in the capacity of a Data Analyst.

However, if you happen to go a step further and build a recommendation algorithm systems which recommends matching booties for cardigans for the small ones, you are largely working in the capacity of a Data Scientist.

Having said that, the two positions can be accepted as being complementary to each other. This is especially because there are a number of arenas wherein their roles overlap. However, the divergence is essentially at the point of the two possessing different levels of coding/programming expertise.

Why should you think of becoming a Data Scientist?

So you are concerned about initiating a shift from being a Data Analyst to Data Scientist; however, what motivated you to think about this transition? What made you think that a shift from a Data Analyst to Data Scientist Career Path can be more rewarding? The answer lies in understanding the factors which make the position of a Data Scientist a lucrative and attractive career option. 

  • Given the kind of benefits that organizations can reap from Data Scientists, the latter happens to be in huge demand across sectors. Moreover, their demand often outstrips the supply and they are considered as assets. 
  • One major reason which often allures individuals in thinking of a career as a Data Scientist is the handsome pay package which accompanies this job role. Their annual average salary range in the United States is held to be around $60,000 to $130,000 (approximately). 
  • The field of Data Science is an extremely dynamic one. This implies that instead of being marked by monotony and boredom, Data Scientist have the opportunity of indulging in resolving new and fascinating problems on a regular basis. This might be in the form of building a recommendation algorithm from scratch, a text classifier which sifts toxic comments or an image recogniser and so on. 
  • Most importantly, one major reason for which you can think of honing your skills for upgrading from Data Analyst to Data Scientist or from Business Analyst to Data Scientist, is the relevance of the latter.

From Data Analyst to Data Scientist: A look at this Shift

Any answer to the question of how to go from Data Analyst to Data Scientist cannot be a universal one.

However, in this section, we shall; try to trace a rough trajectory of how to move from Data Analyst to Data Scientist. Let us look at some of these practical steps of transition. 

  • Understand the field of Data Science

Before you decide to take the plunge into the path of initiating a career transition from being a Data Analyst to Data Scientist; it is important to be clear of the what the field of Data Science is all about and what this job role would demand from you as a Data Scientist.

It is not simply important to acquire new and sharpen your existing skills in line with those of a Data Scientist; but it is equally important to accept the fact that apart from proficiency in mathematics and statistical knowledge, it will be equally important to possess the right bent of mind by which you will be able to look at business problems from the Data Scientist position. Hence, it will be important to hone your critical thinking skills. 

Additionally, it will be important to be clear of the roles and responsibilities of a Data Scientist. This roughly includes:

  • Data Analysis, Data Mining, Data Cleaning and building ETL pipelines
  • Building predictive models using ML algorithms as well as evaluating them
  • Testing and continuously improving the accuracy of Machine Learning models which have already been built
  • Developing Automation tools and strategies 
  • Developing high-end Data Visualizations
job responsibilities of a data scientist
  • Acquire Proficiency in Coding

Being skilled at coding is one of the indispensable skills of being a Data Scientist and hence, an important consideration as you seek the transition from Data Analyst to Data Scientist.

In the capacity of a Data Analyst, you may not be required to possess high-end coding skills; however, this becomes a necessity as a Data Scientist. You need to be proficient in dealing with data within the framework of different programming environments.

Understanding the syntax of programming languages as well as being able to implement statistical and mathematical concepts using in-built functions is crucial as a Data Scientist. Herein, coding skills come really handy. 

  • Enroll in a Structured Course

Applying for a full fledged Data Science course is definitely a great idea as it not only helps in providing you with certified recognition which looks good on your resume but also helps in building your foundational grasp over the discipline. You can even consider computer science programs which are launched in collaboration with reputed universities. 

Additionally, you can also opt for specific niches. This implies that you can take up introductory courses in important aspects of Data Science, such as Machine Learning, Data Visualization, Deep Learning and so on. 

  • Acquiring expertise in handling the Tools of Data Science

So you are thinking of initiating a shift from being a Data Analyst to a Data Scientist; however, this would be rendered extremely difficult if your fail to acquire expertise in handling some of the prominent tools of the Data Science trade. Let us look at some of the most prominent tools which are crucial for Data Scientists. 

  • R and Python

R is one of the foremost tools which is used for data modelling and statistics. Python is an object-oriented, interpreted programming language, is open source and is easy to maintain, read and write. 

  • Tableau

It is considered to be one of the most efficient tools in producing lively Data Visualizations and working on live-data sets and producing reports which can be shared across desktop and mobile platforms, embedded in an application or within a browser.
