Data Analytics is a subset of data science that process and analyzes a large amount of data to give meaningful insights and solutions for organizational problems. It begins with data collection, cleaning, statistical data analysis, interpretation, and sharing of results. The outcomes of data analytics are reliable and exhibit immediate progress in the business.
Data Analytics has four levels of analytics listed below.
- Descriptive Analytics – It gives insights based on historical business data about market trends and patterns.
- Diagnostic Analytics – This level is to identify the root cause of events that halt the growth of a business.
- Predictive Analytics – This level uses statistics to predict the future of any business
- Prescriptive Analytics – It analyzes past data and makes proposals to proceed further in the industry.
Data Science is the umbrella term that includes data analytics along with data engineering, data mining, and other related disciplines. It deals with large volumes of data using machine-learning algorithms or predictive modeling processes to give valuable insights. Data Science is constantly changing and developing. However, Data science relies on the following concepts, which are the pillars of data science.
- Domain Knowledge – This indicates the knowledge about the business, product, or service and its customer base.
- Math & Statistic Skills – These skills are necessary to analyze and interpret data to get insights and valuable solutions.

10 Key Points to Choose Between Data Analytics and Data Science
As we know, Data Science is a broad field with different disciplines like machine learning, statistics, and programming, whereas Analytics is a subset of data science. Data science has more scope compared to data analytics. Moreover, data science is a research-oriented field, while analytics is a practical-oriented one.
Data scientists work on large data sets to give new conclusions and better tools for analyzing data. Data Analytics is a more focused domain in which data analysts work on the same data sets to offer actionable insights to the organization. Data Science does not give answers to any specific question.
Instead, it guides the organization with the insight to frame the questions needed for the business to grow. Data Analytics always works with questions in hand. Data Analyst work to discover the answers to the questions asked. If you are interested in a more practical-oriented job, you can choose data analytics. Most data scientists start their work as data analysts and then upgrade themselves.
2. Data Types in Data Analytics and Data Science.
Data Science handles structured and unstructured data, while data analytics deals only with structured data. Unstructured data has no specific format. It represents the bulk of business data in its native form with no predefined model and is not stored in a structured database.
Unstructured data is collected, stored, and managed quickly. It includes images, videos, emails, social media posts, reports, web pages, and presentations. Specialized tools like NLP and data science experts are mandatory for analyzing unstructured data.
Structured data is well-organized data with a persistent order and conforms to a predefined model. It includes data generated at colleges, universities, banks, companies, etc., and is stored using SQL, MySQL, Oracle DB, and SQLite. It can be handled by data scientists as well as data analysts.
As unstructured data is in its native form and supports massive storage, the importance of unstructured data is increasing. Many businesses prefer this data type for their data management as it gives a deeper understanding of customer behavior. This increases the demand for data scientists compared to data analysts.
3. Requirement of Statistical Skills
Both need knowledge of statistics to analyze data. Statistics is the basis of machine learning algorithms to capture data patterns and translate them into meaningful insights. It also helps with data preprocessing and feature engineering.
Statistics aids data scientists and analysts in visualizing numbers to figure out the trends in quantitative data. Statistics are mathematical analyses of big data and are broadly classified into two types.
1. Descriptive Statistics – Summary Statistics
This type gives an overview of an organization’s data. It helps to review and summarize data understandably. It does not provide insights into decision-making and the growth of a business.
2. Inferential Statistics
This type of statistics interprets data, identifies patterns, and helps to build predictions for decision-making. It suggests valuable insights to achieve organizational success.
Statistical skills help data scientists and analysts confirm the validity of the analysis and also to avoid logical errors. The level of expertise in statistics may vary depending on the job role and the data handled. However, Statistical skills are mandatory for data scientists and analysts. If you are not comfortable and confident in statistics, then it is of no meaning to pursue a career in the data field.
4. Programming Skills
Both Data Analytics and Data Science require programming skills to clean, process, and transform raw data into valuable insights. A data scientist with programming skills or a software background is a more relevant candidate. Their expertise in software makes them not depend on other outside resources.
Advanced object-oriented programming is the most important skill needed by data scientists as they have to handle large data sets, write SQL queries to a database, understand black box tools, and do data cleaning. A Data Analyst also needs programming skills but only a basic level of expertise is sufficient.
The main responsibilities of a data analyst are focused on data crafting and presenting. However, practicing analyzing tools and algorithms, require programming skill. This skill can also help them to perform advanced data analysis without the support of a programming expert. Moreover, programming expertise is very much needed for data analysts who aspire to be data scientists in the future.
5. Coding Languages
Data Analysis uses coding languages like python and R for data analysis. Recruiters expect expertise in any one of the two languages even from an entry-level data analyst. Python is a general-purpose language, which is predominantly preferred for data analysis in the business world.
R is a language for data analysis and visualization. It is mostly preferred by academia for research and the finance industry. In addition, data analysts also require knowledge of SQL, RDBMS, and Oracle to extract data from databases and perform data wrangling and presentation.
The coding language is selected based on the data set provided by the industry. For example, in the retail sector, python is preferred to build trust by providing valuable suggestions to customers. IoT applications prefer languages like C and C++.
So, to kick start a career in data analytics and data science, knowledge in any one of the above-mentioned programming languages is mandatory. Online certification in any one of the coding languages will make you out shine from your competitors.
6. Career Growth
In the digital era, data is everywhere, and every business, regardless of its size, searches for people who can handle data effectively and devise constructive ways to develop the company. Data Analytics and Data Science are two different career paths in the data field.
When you chose Data Analytics, you start your career as an entry-level analyst in any industry and after a few years, you can become a specialist in that industry and can take up roles like financial analyst, health analyst, and so on. Moving on the ladder, you can expect yourself to be a senior analyst or an analyst manager in the data industry.
