Data Scientist

Here are the tools that will help every data scientist to showcase their sharp mind and innovation in this competitive world.

Data science and data scientist’s job market is constantly evolving. Every year, there are so many new things to learn. While some tools rise and others fall into oblivion, it becomes highly essential for a data scientist to keep up with the trends and have the necessary knowledge and skills to use all the tools that make their job easier.

Here are the top 15 tools that every data scientist should bring to work to become more effective at their job.

Problem-Solving Knowledge

For a data scientist, their mind is one of the best tools that keep them one step ahead of the competition. Because data science is the field where you have to deal with different roadblocks, bugs, and unexpected issues every day. Therefore, if you do not have problem-solving skills, it will become difficult for you to continue with your work.

Programming Languages

Programming languages allow data scientists to easily communicate with computers and machines. They don’t need to be the best developers ever, but data scientists should be strong at it. Python, R, Julia, and SQL, and more, are the programming languages that are widely used by data scientists.


This convenient data science tool is an undertaking grade arrangement that tends to each expected requirement for AI and machine learning. With DataRobot, data scientists get everything rolling with just a few clicks and support their organizations with components, for example, robotized AI or time-series, AI tasks, and more.


TensorFlow is crucial if you are interested in artificial intelligence, deep learning, and machine learning. Built by Google, TensorFlow is essentially a library that helps data scientists to assemble and prepare models, etc.


With the help of Knime, data scientists can integrate elements like machine learning or data mining into data sets and create visual data pipelines, models, and interactive views. They can also perform the extraction, transformation, and loading of data with the intuitive GUI.

Math Skills

In data science, statistics and probability are crucial. This tool help data analysts to understand what they are working with and guide their exploration in the right direction. Understanding details additionally guarantee that the analysis is valid and there are no logical errors.

AI and Machine Learning

Companies always give priority to those data scientists that know machine learning. AI and machine learning give data scientists the power to analyze large volumes of data using data-driven models and algorithms aided with automation.

Data Visualization

Data science involves a lot of precise communication, therefore having the ability to tell a detailed story with data becomes very important. In that case, data visualization might be essential to your work as analysts depend on graphs and charts to make their theories or findings easier to understand.


RapidMiner is used to prepare models from the initial preparation of data to the very last steps, for example, analyzing the deployed model. Being an end-to-end data science package, RapidMiner offers massive help in areas like text mining, predictive analytics, deep learning, and machine learning.


Python is one the most powerful programming languages for data science because of its vast collection of libraries like Matplotlib and integration with other languages. Matplotlib’s simple GUI allows data scientists to create attractive data visualizations. Thanks to multiple export options, data scientist can take their custom graph to the platform of their choice easily.


D3.js allows data scientists to use functionalities for creating data analytics and dynamic visualizations inside browsers and it also uses animated transitions. By combining D3.js with CSS, a data scientist can create beautiful transitory visualizations that assist in implementing customized graphs on web pages.


For simulating fuzzy logic and neural networks, every data scientist makes use of MATLAB. It is a multi-paradigm numerical computing environment that assists in processing mathematical information. MATLAB is a closed-source program that makes it easier to carry out tasks like algorithmic implementation and statistical modeling of data or matrix functions.


Excel is probably the most widely used data analysis tool because MS Excel not only comes in handy for spreadsheet calculations but also data processing, visualization, and carrying out complex calculations. For data scientists, Excel is one of the most powerful analytical tools.


Nowadays, organizations that focus on software development widely use SAS. It comes with many statistical libraries and tools that can be used for modeling and organizing data. SAS is a highly reliable language with strong support from the developers.

Apache Spark

Apache Spark is one of the most used data science tools today. It was designed to deal with clump and stream processing. It offers data scientists numerous APIs that assistance to make rehashed admittance to information for AI purposes or capacity in SQL and others. It’s most certainly is an enormous improvement over Hadoop, and it can perform multiple times faster than MapReduce.
