With the increase in the data, its scope increases and so do the people working in it. Each person has its own realm of working, whether they are freshers or the people at the top positions. Same goes with the booming field of data science. Say if you knew who is a data analyst and who is the data scientist? Do you know what exactly do they do? What if I tell you that the person who works on structuring the data isn’t the same who works on the predictive modelling? What is the criteria to distinguish between these two roles? Why are these two roles different?

Seems like too much of brain raking exercise? Don’t worry!! Continue reading so that by the end of the post you will be able to clear the difference to others.

The “Who” is the Question….

Who is a Data Analyst?

Data analysts are the ones who comb the data and use it to come up with the replies to the queries posed in front of a business. The results thus derived from the analysis are used for making important business decisions. You can also come upon the title of Business Analyst being used interchangeably in this post. So, don’t confuse them as a separate position. It is just another name for Data Analysts. 

Data analysts are the Detectives with a magnifying glass in their hand, always searching for that right set of data which will reveal the insights.

So, here is a summary of some of the tasks that a data analyst is typically expected to do.

  • Clean and organize the data
  • Use descriptive statistics for a wider analysis of the available data
  • Analyze the discovered trends in the data
  • Develop dashboards and visualizations to assist business with the interpretation of data and making decisions on its basis
  • Present the outcome of the analysis to the internal teams or clients

Who is a Data Scientist?

Data analysts move up the ladder to become data scientists. Ok!! Yes, I agree these are the most sought after people.

But do you know they are the Unicorns. Why? It is not that easy to spot a skilled one.

But with the increase in the awareness and relevance about the job, it will not be that tough to spot them now.  Data scientists are the experts in statistics and machine learning. They develop machine learning models that can predict and solve crucial business questions. This doesn’t mean that a data scientist doesn’t know the job of a data analyst; he does. Together with it, a data scientist possesses an in-depth knowledge of the skills to clean, analyze and visualize the data sets and is able to tutor and enhance models of machine learning.

Here are some of the tasks that a data scientist typically performs.

  • Evaluation of statistical models to judge how valid is the analysis of the models
  • Developing improved predictive algorithms using machine learning
  • Constantly testing and enhancing the efficiency of machine learning models
  • Creating the data visualizations to make a summary of an advanced analysis 

How is the Unicorn different from the Detective?

Clearing the blurred lines between the two data professionals…..

Not every person working in the field of data science is a data scientist, as opposed to the common assumption. In this section, we will discover how our detective is different from the unicorn.

  1. Data analysts are the ones who do the research and produce insights, while the data scientists are the ones who communicate these findings to the business stakeholders who have a non-technical side. Imagine how complex is everything in the data world. Data analysts also do the storytelling but only to the data scientists or the ones who are technically proficient. Data scientists convert these results in a graphical representation (charts, graphs, images or even easy words) to make it comprehensible.
  2. The aim of data analysts is to develop answers while data scientists develop questions using the available data and make a decision as to which answers will prove to be beneficial for the business.
  3. When the problem in a business arises, data analysts simply address it, while data scientists make a precise prediction of the business value after the problem is solved.
  4. Data scientists have the ability to sense the unknown facets of the business. Remember, they predict? Data analysts work on the evident facets of the business with a fresh approach.
  5. Data analysts analyze the data coming from one source, such as the CRM, whereas data scientists analyze the data coming from numerous disconnected sources.

The Good Old Table View of the Comparison

*The tools shown in the above processes are not the only ones used; there are many other ways/tools to carry out the above procedures. There might be 1 or even 2 tools to carry out these processes. It depends on the businesses and the organizations.

Data analysts and data scientists are imperative for the success of a business and with both working in unison, there is nothing that can obstruct the organization’s aim to achieve the target objectives. I hope that by now the confusion, regarding who is the unicorn (data scientist) and who is the detective (data analyst), must have vanished into thin air. Having a clear vision always helps you in moving ahead in the right direction with a focused approach.
