As said earlier, Data Science is a fiercely growing field because of the ongoing amount of data around the world and the ever-expanding demand for data scientists. Suppose you aspire to make a career in Data Science; in that case, you’ll get an amazing opportunity to work on evolving technologies such as ML and AI, including Edge Computing, Blockchain, Serverless Computing, etc. If you’ve been convinced to make a career in Data Science due to its growing demand and high pay scale. You must be curious to know data scientist opportunities, including data science prerequisites.
As you know what data science is, next, we’ll focus on the life cycle, which contains five separate stages, each with its unique tasks -
As the name suggests, Data Science is all about data. Therefore, the most crucial requirements to be a data scientist are - to have an affection for data, understand the data, and have the capability to deal with data.
Data scientists need to assess large data sets, including structures and unstructured ones. Combining computer science skills with maths and statistics, they process, analyze and model data to present meaningful outcomes.
To do this, they require a variety of data science prerequisites that are mainly categorized into two types -:
The minimum educational requirement to be a data scientist is a graduation degree in computer science, IT, maths, statistics, engineering, or any other relevant field. Furthermore, inclining statistical analysis and coding will be an added benefit for you to master the skills required for becoming a Data Scientist.
Even though having a bachelor’s degree is the minimum prerequisite, most businesses prefer candidates with higher academic qualifications, i.e., a minimum master’s degree, as stated by the US Bureau of Labor Statistics.
A solid educational background is crucial to acquire in-depth knowledge to pursue a successful data science career. You can also enroll in online data science training and certification courses to stay updated with the latest technologies and skills. These are the basic data science prerequisites one should be aware of before starting a career in data science.
1. SQL Databases: Analyzing thousands of job descriptions for data science posted on LinkedIn, one prerequisite for data science that topped the list was SQL, in around 57% of job postings. This language is used for managing and querying data stored in RDBMS and reading, retrieving and updating, inserting new data, or deleting existing data. SQL language also helps in data structure transformation and performing analytical tasks.
Businesses expect candidates should be able to write complex SQL queries to get insights from data. A necessary prerequisite for data science.
2. Hadoop- Hadoop is another important prerequisite for data science cited in approximately 49% of data science job descriptions. However, it's not a compulsory requirement, but still one of the highly preferred skills by recruiters.
When working as a data scientist, sometimes you might come across a situation where the quantity of data you’ve got exceeds your system's memory. At this time, you will be required to send that data to various servers; this is where Hadoop comes into play. This platform can quickly transfer data to different points in the system.
3. Python- Python was the 3rd most in-demand data science skill, found in 39% of job listings. Currently, it is the most preferred programming language among data scientists. Since Python for data science is a very flexible and easy-to-use language inside almost all the data science processes, such as data mining, operating embedded systems, etc., it's highly popular. Python library has Pandas that can be used for data analysis and for carrying out any task, from plotting data using histograms to importing data. Learning programming languages is compulsory, among others, for data scientist prerequisites.
4. R Programming- Next important prerequisite for a data scientist, after Python, is R Programming, specially designed for data science and was cited in around 32% of job listings. It could be used to resolve any type of data science-related issue. R Programming is mostly used for solving statistical issues.
But having said that, its learning curve is very steep and difficult to master, mainly if you already have mastery in another coding language.
This language can install machine learning algorithms and give different statistical and graphical methodologies such as time-series analysis, clustering, standard statistical tests, etc.
5. ML and AI- ML and AI are also essential data scientists prerequisites
Machine learning help in assessing huge amounts of data with the help of algorithms, and this language could automate a major part of data scientists’ job. As just a small no. of data scientists are highly skilled with advanced ML techniques such as adversarial learning, reinforcement learning, the neural network in data science, etc.
Most proficient data scientists understand advanced ML techniques like recommendation engines and NLP (Natural Language Processing). Do you wish to stick out from the crowd and be at the top level? Knowledge of ML techniques is a must.
6. Mathematics and Statistics- Another important prerequisite for data science is Mathematics and statistics because statistics and probability are required for data manipulation, visualization, transforming features, model evaluation, data processing, etc. Multivariable calculus is used for building machine learning models, and for data processing and transformation, model evaluation linear algebra is used. For representing a data set, the matrix is used.
7. Apache Spark- Similar to Hadoop, Apache Spark is a big data computation framework; the only difference between the two is that Spark is relatively faster. Hadoop reads from a disk and writes to a disk; on the other hand, Spark grabs its numbers inside the memory of the device, making Spark faster than Hadoop. Spark is specifically designed for data science to execute complex algorithms quickly, helping you save time while processing data. Additionally, it can also help data scientists manage large, unstructured, and complicated data sets.
8. Data Visualization- Is also another very essential requirement for data science. Simply put, it involves representing data visually using graphs and charts. A data scientist should be able to present the data graphically with the help of charts, maps, etc. Data visualization is a crucial prerequisite for data science.
9. Excel and Tableau- Are the other 2 most important requirements for data scientists, as both are essential for understanding, manipulating, analyzing, and visualizing data. Excel is useful when a lot of manipulation and calculations must be done on the data.
You’ll need Tableau when you collect data at one location and show it with the help of powerful visualization on a dashboard. A blend of both could be used when all the crucial calculations can be performed on Excel, and the resulting data set can be imported to Tableau for further analysis and to get a clearer vision. One should be thorough with all the data science prerequisites to embark on a successful journey.
Data Science Training - Using R and Python
Data scientists are responsible for data extraction, manipulation, pre-processing, and forming predictions based on the data. So as to do that, a data scientist must work with different statistical tools and coding languages.
We’re sharing a list of top data science tools for your reference.

The work patterns of data scientists and data analysts can be similar yet different. Both find trends or patterns in data to reveal new ways for organizations to make better decisions. While data analyst examines data to uncover meaningful and insightful trends, often using tools like SQL and Excel, data scientists build complex predictive models and develop algorithms along with analyzing data. They use programming languages like Python and R to extract their data, make predictions for the future, and create data-driven products.
Data analysts are often expected to support teams with predefined goals. In contrast, data scientists form their questions about data, spend more time developing models, using machine learning, and bridge the gap between data analysis and ML to solve complex problems and drive innovation.
