Data Science Vs. Data Analytics: An In-Depth Comparison Of Similarities And Differences

There’s no question that data is transforming the way we do business. In 2025, the annual revenue from big data markets worldwide is expected to be a staggering $68 billion USD.

The rise of big data–an immense amount of information processed, analyzed, and harnessed–offers organizations an opportunity to gain a competitive advantage in their industry. Data science and data analytics allow organizations to improve their customer service, reduce costs, and optimize operations. 

While data science and data analytics share some similarities, they each approach and work with data in distinctive ways.

In this article, we’ll explore the biggest differences between data science and data analytics, the difference between a data scientist and data analyst, and which one might be the better fit for you. 

Data Science Vs. Data Analytics: At A Glance

Data science and data analytics are both crucial in the processing of large amounts of data for businesses and organizations worldwide. While both data science and data analytics work with big data, they focus on different aspects of it. 

Data science explores data in its earlier and more chaotic form. According to IBM, data science is multidisciplinary. It combines several different fields such as mathematics, statistics, and computer science.

Data science involves the preparation stages of data’s life cycle such as acquisition and extraction as well as the communication stage which involves reporting findings and insights to shareholders.

On the other hand, data analytics deals with a specific stage in the life cycle of data science: analysis. It focuses specifically on answering specific questions and concerns.

Data analytics is concerned with how businesses can use the information and insights learned from big data to solve issues, reach certain goals, and optimize performance. The term data analytics encompasses all types of data analysis.

Since analysis is a part of the data science life cycle, a good way to differentiate between data science and data analytics is by defining data analytics as an important branch of data science.

“Data science lays out the groundwork for data analytics to extract meaningful insights from the huge amount of data gathered by organizations,” explains  Nora Simmons, a technical writer at Origin Writings and Brit Student

What Is Data Science?

Data science is a multidisciplinary approach to big data that combines several STEM fields such as computer science, mathematics, and statistics.

Its purpose is to prepare the massive amounts of data collected for data analysis in order to extract as much valuable information as possible for the organization.

To fulfil the roles effectively, data scientists have a deep understanding of each phase of the data science life cycle. The data science life cycle consists of the following five stages. 


  • Digitizing data from the real world (data acquisition)
  • Retrieving data from multiple sources (data extraction)


  • Storing data in a secure location (data warehousing
  • Fixing or removing incorrect and corrupt data (data cleansing)
  • Converting raw data into a machine-readable form (data processing)


  • Sorting through large volumes of data to find patterns and other useful information (data mining)
  • Labelling data (classification
  • Grouping similar data entries together (clustering
  • Creating a data model to visualize the data and to store it in a database (data modelling)
  • Presenting data in a simplified and concise manner (data summarization)


  • Exploring the data in search of trends and p (exploratory data analysis)
  • Testing your evidence to confirm your exploratory data analysis (confirmatory data analysis)
  • Determining the likelihood of certain trends and future outcomes based on historical data (predictive analysis
  • Examining the relationships between variables and identifying which variables carry the most influence (regression
  • Using artificial intelligence, specifically natural language processing, to uncover insights from unstructured data (text mining)
  • Discovering and understanding the meaning behind data sets (qualitative analysis)


  • Submitting a summary of your findings from the data in an organized format (data reporting
  • Presenting information in a way that’s easier to understand with visual context (data visualization tools
  • Producing a report on the company’s activities, performance measures, and other information that helps with better decision-making (business intelligence

Due to the advantages, it offers to any organization, a growing number of businesses are turning to data science and data scientists. 83% of business executives pursue big data for a competitive advantage.

What Is Data Analytics? 

While data science comprises all five stages of the data science life cycle, data analytics focuses mostly on the analysis and communication phases. Data analytics or big data analytics is the analysis of raw data in order to extract valuable information from it.

Its purpose is to organize big data in a more meaningful way, extract intelligence from data, and report any notable patterns that could help the organization with its decision-making process. 

All types of data analysis fall under the broad category of data analytics. However, its four main components are: 

Descriptive Analytics 

  • Answers that question, “What happened?” 
  • Examines current and past data to understand the business more 
  • Considered to be essential for business intelligence 
  • Used as the foundation for diagnostic analytics, prescriptive analytics, and predictive analytics 
  • Identifies notable trends through tools such as Microsoft Excel 

Diagnostic Analytics 

  • Answers the question, “How could this happen?” 
  • Focuses on the causes behind a trend or relationship between variables 
  • Usually follows descriptive analytics and is used to support a decision with convincing data 
  • Employs techniques such as hypothesis testing, causation or correlation, and diagnostic regression analysis 

Predictive Analytics 

  • Answers the question, “What’s going to happen?” 
  • Uses historical data, machine learning, modelling, and data mining 
  • Predicts future risks and opportunities for the company based on data trends 
  • Builds models capable of forecasting future events 
  • Valued across several industries including: 
    • healthcare (used to detect chronic illness and care for patients)
    • finance (used to prevent fraud and determine credit risk)
    • human resources (used to predict the health of the labour market) 
    • retail (used for product recommendations and sale forecasts) 
    • marketing (used for marketing campaigns) 

Prescriptive Analytics 

  • Answers the question, “What actions should be taken in order to reach a certain solution or goal?”
  • Uses tools such as machine learning, neural networks, graph analysis, simulation, and complex event processing 
  • Collects data from descriptive and predictive sources to create models 
  • Provides recommendations on how to grow as a business and optimize performance 
  • Identifies the best course of action for the organization 

A study found that companies that take advantage of data analytics to inform their decision-making are 23 times more likely to acquire more new customers than other companies in their industry that do not analyze big data. 

“As a result of its ability to boost customer acquisition and improve business performance, more and more companies are taking advantage of data analytics,” according to Mary Ramirez, a business writer at Write my X and 1 Day 2 write.

“Soon, it might be impossible for some organizations to keep up with their competitors without using big data analytics.”

Similarities Between Data Science And Data Analytics 

Both data science and data analytics allow organizations to gain a competitive advantage in their industry. Here are some more similarities between data science and data analytics. 

Interpret Big Data 

Data science and data analytics sort through large volumes of data to find patterns and relationships. Though their scope may be different, data science and data analytics both try to make sense of data. 


Data science and data analytics frequently borrow techniques and tools from highly technical fields such as computer science, statistics, and information technology. 

Impact On Other Functional Areas

Findings from data science and data analytics often affect marketing, sales, product development, and operations.
