As per the Harvard Business Review, Data science jobs are amongst the most sought after and lucrative careers of the 21st century. Apparently, it has become a major and significant part of many businesses like marketing, risk control, agriculture, fraud discovery, retailing analytics, and common policy.

Data scientists use various scientific methods, processes, algorithms, and systems to extract knowledge from structured and unstructured data. Their concept is similar to data mining and big data, where they use the most powerful programming systems and algorithms to solve problems. The tasks performed by data scientists demand them to identify relevant questions, collect data from various different sources, organization of data, the transformation of data and communicating these findings for a better business outcome/ solution.

A data scientist is responsible for manipulating, extracting, pre-processing and generating predictions out of data and he requires a plethora of statistical essential data science tools and programming languages to achieve that goal.

Data Science Tools

Let’s have a look at a few of the top essential tools for working with data:


This one is probably one of the most essential tools for working with data and Data Analysis but not one of the ideal tools for non-enterprise levels. Excel provides you with many formulae, tables, filters, slicers, etc. and it gives you the liberty to make your own custom functions and formulae as well.

Excel is a powerful analytical tool for data science mostly used for spreadsheet calculations and it is widely used for data processing, visualization, and complex calculations.

Open Refine

This is often considered as one of the most popular and essential data science tools users need to analyze big data. Earlier it was known as the Google Refine. Open refine provide its users with many compelling characteristics that any data scientist may require during the course of their usage.

open refine data science tool

Open refine has numerous compelling characteristics that any data scientist may demand as it provides clustering, editing blocks with added values and prolonging web services. It also permits data scientists with many essential data science tools where they get to connect among several datasets. Open Refine can handle outlines in a particular domain, and that space is included in a file index with sub-directories.

Natural Language Kit

NLTK is widely used for numerous language processing techniques like Tokenization, tagging, stemming, parsing and machine learning.

Python language provides its users with a useful collection of libraries called NLTK (Natural Language Toolkit) which comprises more than 100 corpora which are a collection of data for building a machine learning model

It comes with many useful applications such as Word segmentation, Machine translation, Parts of speech tagging and text to speech recognition. As it is evident that Natural Language Processing is the most used field in Data science and clearly one of the most essential data science tools.


MATLAB’s only limitation is a closed-source software but its easy integration for enterprise application and embedded systems make it a very essential data science tool. This data science tool is mostly used in scientific disciplines which allows matrix functions, algorithmic implementation and statistical modeling of data. MATLAB graphics library can create powerful visualizations, image and signal processing making it a very dynamic and essential data science tool.

Although SAS is a reliable data science tool but the only drawback being that it is an expensive tool, it needs expensive up-gradation to the base pack and can be used for larger industries only and it falls short in comparison to many new modern open-source tools available.

Apache spark

Spark or Apache spark has many Machine Learning APIs which makes it an essential data science tool that can help Data Scientists to make powerful predictions with the given data.

It is a powerful analytics engine specifically designed to handle batch processing and steam processing and it gives many APIs which are programmable in Java, Python, and R for repeated access to data.


It is considered better than Hadoop and other big data platforms and can perform faster than MapReduce and its most powerful feature is its conjunction of spark with Scala programming language based on JVM (Java Virtual Machine) which is cross-platform in nature.

Apache Hadoop

Apache Hadoop is an open-source data science tool that allows users to store and manage monstrous data-sets on clusters of stock hardware.


It is authorized under the Apache License 2.0 and gives its users the capability to manipulate implicitly infinite coexisting assignment


This is an open-source powerful tool based on IPython completely free of cost helping developers to create open-source software. It runs on the cloud and provides an online environment called COLLABORATORY for storing the data in Google drive Jupyter is an interactable environment which gives dynamic tools for storytelling through interactive computing used for writing live code, visualizations, and presentations.


Jupyter is a widely popular tool that is designed to address the requirements of Data Science using Notebooks where data cleaning is done, statistical computation, visualization, and predictive machine learning models


BigML is also considered amongst the most essential data science tools for providing a user-friendly web-interface where one can create a premium account as per our data needs.

BigML uses a machine-learning algorithm like clustering, classification, time-series forecasting by providing a cloud-based GUI environment that is easy to interact with.
