Data science and data analytics are often used interchangeably, but they are not the same. The difference between data science and data analytics is in their functions.
While data science may be the broader umbrella term, Data Analytics is more of a concise and specific part of Data Science. Although there is a distinct difference between data science and data analytics, both functions still go hand-in-hand. If you’re looking to find a career in either data analysis or data science, then this is the perfect guide for you. Read on as we delve deeper into the details of Data Science and Data analytics and also highlight the key differences between the terms.
What is Data Science?
Data Science is a multidisciplinary method that aims to make sense of the humongous pile of raw data collated daily. It includes an amalgamation of scientific and quantitative methods of Statistics, Engineering, Computer Science, Machine Learning and Artificial Intelligence to name a few. According to Harvard Professor Dustin Tingley, “Data science is a discipline that’s built on a foundation of critical thinking.”
It aims to pose questions through unorganised or organized data sets and also aims to answer them. Through a series of data tools like Hadoop, Spark etc, it aims to build predictive models and shape data.
Data science mainly prioritizes collecting or building the raw data, cleaning it, and then organizing it into various data sets.
What is Data Analytics?
To put it simply, Data Analytics aims to answer the questions put forward by Data Science. While data science aims to collect and build upon raw data, clean it and organize it into various data sets – Data Analysis is used to extract Insights from these organized Data Sets. They seek to explore these data sets and predict implementable models that could help Organisations and businesses fulfil their objectives. Data Analytics is done using a wide range of tools, techniques and methods that differ depending on the type of analysis that is being conducted.
There are four major types of analytics:
- Descriptive Analytics aims to look at the data and describe and understand something that has already happened
- Diagnostic Analytics aims to answer the “why” behind a phenomenon
- Predictive Analytics uses past trends, historical data and strategic assumptions to project what will happen in the future
- Prescriptive Analysis identifies the measurable and well-thought-out steps that an organization or a business must take to reach their future objectives.
Data Science Vs Data Analytics
Although Data Science and Data Analytics both deal with data, the difference between data science and data analytics is in what kind of data they deal with. Data Science is an umbrella term for everything pertaining to Data while Data Analytics has a more specific scope.
Data science acts as the investigator. It mines and cleans data into different sets and begins to pose different questions based on the said data sets. While Data Analysis is the way of answering the questions that data science poses and also finding implementable insights through the datasets found.

The main difference between Data science and data analysis can be said that Data analysis focuses more on seeing the historical data and past trends. It uses assumptions to bring out the best possible solutions and future steps for the organization/business. While Data Science is focused more on Machine Learning and Predictive Modelling. The latter focuses on finding the relation between vastly different data sets, while the latter aims to discover the specifics based on the different insights found.
Thus Data Analytics can be said to be a branch of Data Science that focuses more on the post-processing of the data sets found by data science.
Data Scientists vs Data Analysts
Data scientists and Data Analysts both work with Big Data. Data scientists utilize a variety of Complex Mathematical tools like mathematics, Statistics and Machine Learning. They gather structured or unstructured data from many contrasting sources. After collection, this raw data is processed and converted into a format where it could be easily analysed. They clean and validate data to ensure that it is accurate, uniform and complete.

Data Analysts on the other hand take these large piles of data and explore them to discover implementable insights. These insights can help an organization or a business to fulfil its goals and objectives. They spot trends, make forecasts for the future and gain a better understanding of the collated data. Data analysts are similar to a fusion of Data Scientists and Business Analysts. Once they’ve figured out their findings, they also need to communicate them in the simplest ways possible to both technical and non-technical people. This is why they use various infographics, charts, stories etc to explain their findings.
Now the difference between Data Scientists and Data Analysts may be confusing since essentially they both dabble with data and have inter-connected responsibilities and functions. The major difference is in the tools that Data scientists and data analysts use. Machine learning is a major part of a data scientist day-to-day life while not so much of an analyst’s.
To put it simply, a data analyst’s daily routine consists of daily analysis and providing reports almost every day. And data scientist’s routine consists of designing new ways of storing and manipulating data. The former works on existing data sets while the latter designs the data sets which would later be used by the analysts.
Data Scientists Vs Data Analysts: Skills
The core skills of Data Scientists and Data Analysts mainly differ in the type of tools that they use to conduct their daily responsibilities. While there may be some overlap in their analytics functions, they majorly differ in the quantitative tools section. Data scientists typically use programming languages like Python, R, Java, etc. while data analysts use tools like SQL Database and Excel.
The main skills of a data analyst are:
- Should be well-versed with Statistics and Probability
- Should be familiar with programming languages like R or Python programming
- Should have expert knowledge of Excel and SQL database
