The field of data analytics is throbbing with innovations every day. Much of the effort of an organization goes waste if an individual’s role is not adequately defined. Identifying the different roles and how to measure the importance of each is one of the biggest challenges faced by the data industry today, as their definition of what they do and how they can change the world has grown tremendously.

This tutorial brings out a clear difference between the two roles. This difference is explained in terms of what they do, how they individually benefit an organization and their typical workday.

Data Analyst

A data analyst is someone who looks at the data and checks it immediately to see whether it will help in answering the business questions for which it was collected. The requirements usually limit their activities.

Some benefits that a data analyst brings to a company are:

  • Income expansions
  • Operational effectiveness
  • Reactive decision making
  • Beat the competition

A data analyst can take up activities that relate to business intelligence. There are no new questions that are answered by an analyst. However, he/she might like to infer some insights from exploratory analysis, report those, and let the business know of some new questions that may be useful for a company’s profit margins.

Roles And Responsibilities

  • These include data querying by using SQL.
  • They perform data analysis and forecasting through Excel. Business data will get analyzed for identifying the correlations and discovering the patterns from multiple data points.
  • They perform the mapping and tracing of data from systems to systems to find out the solution to a given business issue.
  • They make use of business intelligence software to create dashboards.
  • Data Analysts make use of various reporting tools to create data reports that will help business executives with making better decisions.

Usually, data analysts make it to the board member meetings and take up analytics and end up giving presentations, which might result in informed decisions by management. As a member of an analytics team, a data analyst collaborates with other individuals in the same field.

Some other stakeholders include:

  • Business analyst
  • Business Intelligence analyst
  • Data analytics engineer
  • Analytics manager
  • Data scientist, etc.

A typical day in the life of a data analyst involves some activities such as

  • Data collection
  • Data wrangling or Data munging
  • Creation of data models
  • Integration with other sources for data by writing SQL queries
  • Compiling and giving presentations with the help of storyboards
  • Mapping requirements to the results in the form of visualizations

Their activities are centered on improving processes around data collection and its consumption to build reports to improve business.

Data Scientist

A data scientist is an individual with a research mindset and has experience in understanding the data itself. He/she employs knowledge of various subjects such as statistics, mathematics, programming to simplify data problems.

Data science practitioners need to have unparalleled experience in quantitative data analysis, genomics, and machine learning, among many other disciplines.

Data Scientists might not have the same insight as analytic or analysis professionals that both need and involve a sense of validity and objectivity. They keep in mind that their objectivity should not clash with their personal opinion about how their work or the data looks.

Roles And Responsibilities 

  • Data Scientists perform data cleansing and processing by making the use of programming languages such as R and Python.
  • Data Scientists find out the new features of the data and unlock its value.
  • They perform Data Mining through APIs, or by building ETL pipelines.
  • They perform statistical analysis by making use of machine learning algorithms.
  • They work on creating programming and automation techniques such as libraries.
  • Data Scientists find out new business questions that will be helpful.
  • They develop new analytical methods and machine learning, models
  • This role includes data storytelling and visualization.
  • Data scientists’ responsibilities also include correlating disparate datasets.
  • Their responsibilities also include conducting causality experiments through A/B experiments.

On a typical day, a data scientist is seen to be

  • Bringing data from multiple resources
  • Wrangling data
  • Performing exploratory analysis
  • Creating algorithms that can help in explaining the data.

Moreover, the outcome of the work of a data scientist is generally consumed by a data analyst.

Data scientists develop machine learning models, create a proof of concepts, and follow an iterative process to improve them with continuous feedback before final deployment for others to use. They use tools and technologies such as R, Python, Spark, Perl, SAS, etc.

Data Scientist Vs Data Analyst – Key Differences

#1) Objectives

An analysis expert may want to know who the key stakeholders are, how the products or processes are built, etc. The data analyst wants to understand what is being produced and how it is being consumed by different users or business units or functions.

However, a data scientist limits his objectives to the assigned project or projects and focuses more on the aspects of using scientific methods to extract insights from the data sources.

#2) Expertise

A data analyst is a person who gathers and cleans data to identify patterns and explain them to others in the organization. A data scientist is a person who has obtained expertise in algorithms that calculate metrics that humans would not have been able to generate and has identified and describe the data.

#3) Scope of activities

A Data Analyst crunches tons of data and mines the information to conclude. A Data Scientist learns new programming languages, defines new algorithms, and applies them. Data Scientist is more similar to a lead developer and is not limited by the specific requirements, unlike a data analyst.

#4) Results

A Data Scientist goes through a data pipeline and looks at the data, interprets it, makes predictions, and often refines the prediction based on test results and growth rates. A data analyst with a data engineer integrates all the data, tests, validates the results, and makes sure that it’s correct, not the other way round.

Data Analyst Vs Data Scientist Salary

Data Analysts’ average salary can be in the range of $67,377 to $84000, whereas Data scientists’ average salary can be in the range of $79,423 to $162000.
