Data Science: the Definition

Data Science is a broad field that encompasses the use of methodologies, techniques, and advanced tools for collecting, analyzing, and presenting data. The main goal of data science is to extract meaning and insights from large and complex data sets, also known as "big data."

Data scientists use these methods to predict trends, identify patterns, perform categorization, and solve complex problems in various domains, including business, medicine, natural sciences, government, and more. The field integrates several disciplines such as mathematics, statistics, computer science, and behavioral sciences, enabling the exploration and analysis of data in ways that were not possible in the past. This includes tools such as statistical analysis, machine learning, natural language processing, and computer vision.

The ability to understand and analyze data efficiently and accurately is a crucial component in the modern technology world, where vast amounts of information are generated and collected every day.

What does a Data Scientist do?

These are some of the roles and assignments a data scientists do:

  1. Data Collection and Preparation: Data scientists are required to collect data from various sources such as databases, APIs, surveys, etc. They need to handle unstructured or missing data and turn them into clean and organized data sets for analysis.
  2. Data Presentation and Insights: Data scientists need to be able to translate findings and insights from the data into clear and accessible language. This includes writing reports, creating data visualizations, and presentations for different audiences.
  3. Statistical Analysis and Machine Learning: Data scientists use statistics and machine learning methods to explore and identify patterns and behaviors within the data. This may include developing and training statistical models, regression analysis, clustering, and more.
  4. Model Building and Validation: Data scientists build predictive models and determine their accuracy and efficiency. They are required to examine the results of the models through statistical tests and cross-validation.
  5. Collaboration with Technical and Business Teams: Data scientists need to work in multi-participant teams, including engineers, analysts, marketing personnel, and management. They can provide technical guidance and training to these teams.
  6. Business Problem Solving and Strategic Planning: Data scientists work on solving complex business problems and influence strategic decisions within an organization through the data they analyze.

Skills and Knowledge Required to Be a Data Scientist:

  • Knowledge in Mathematics and Statistics: Understanding of statistics, probability, and mathematics is essential for data analysis.
  • Programming and Data Analysis Skills: Proficiency in programming languages like Python and using tools like SQL for working with databases.
  • Machine Learning and Algorithmic Analysis: Understanding of machine learning, including various algorithms and how to implement them.
  • Communication Skills: Ability to translate complex findings into simple language and present them to different audiences.
  • Data Visualization Skills: Ability to present data clearly and comprehensively, including using tools like Tableau or PowerBI.


In short, a data scientist should ideally be a curious and goal-oriented team player who can think critically and solve problems using data while collaborating with their teammates, stakeholders, and, well, users.

What Do You Need to Do to Become a Data Scientist?

To enter the field of data science, it is important to develop a variety of technical and soft skills. For example, knowledge in areas such as programming (Python or R preferred), data analysis, and data visualization, as well as advanced skills in Excel and Tableau. Additionally, skills in planning and organization, quick learning ability, and creative implementation of solutions, along with great attention to detail, are very important. Moreover, the ability to work independently in a fast-paced, changing environment, and clear communication skills, both written and oral, are essential for success in the field.

It is advisable to start with formal education, such as a degree in computer science, statistics and mathematics, or a related field. Upon completion of the degree, you should take a data science course to gain the relevant knowledge and skills for the field itself. Note that the course includes an internship option, which will give you initial experience and apply the material learned in the real world.
