What is a Data Scientist?

In summary, a data scientist is a professional who is skilled in extracting insights and knowledge from data using a combination of statistical, programming, and domain expertise. They use various tools and techniques such as machine learning, statistical modeling, and data visualization to analyze and interpret complex data sets, and communicate their findings to stakeholders in a clear and actionable manner. Data scientists often work in fields such as finance, healthcare, e-commerce, and technology.

Day to day tasks

A data scientist’s day-to-day tasks can vary depending on the industry and company they work for, but some common activities include:

  • Collecting and cleaning large data sets from various sources
  • Exploring and analyzing data using statistical and machine learning techniques
  • Building and implementing predictive models and algorithms
  • Communicating findings and insights to stakeholders through visualizations, reports, and presentations
  • Identifying and solving business problems using data
  • Staying current with new technologies and industry trends

Additionally, they can also be involved in:

  • Developing and maintaining data infrastructure
  • Collaborating with other teams such as product managers, engineers, and business leaders to identify opportunities for using data to drive decision-making and innovation.
  • Participating in design and development of new data products.

Overall, the role of a data scientist is to turn data into actionable insights that can inform and improve business decisions.


Data scientists use a variety of tools to collect, process, analyze, and visualize data. Some commonly used tools include:

  • Programming languages: Python and R are the most popular programming languages used by data scientists for data manipulation, analysis, and visualization.
  • Data storage and processing: Tools such as SQL, MongoDB, Hadoop and Spark are used to store and process large data sets.
  • Data visualization: Tools like Tableau, Power BI, and Matplotlib are used to create interactive visualizations that help communicate findings and insights to stakeholders.
  • Machine learning and statistical modeling: Tools like scikit-learn, TensorFlow, and Keras are used to build and implement predictive models and algorithms.
  • Cloud computing platforms: AWS, Azure, and Google Cloud are popular platforms used by data scientists to store, process, and analyze data at scale.
  • Collaboration and project management: Tools like Jupyter Notebook, GitHub, and Asana are used for collaboration, version control, and project management.

It’s worth noting that the list is not exhaustive and the tools used by a data scientist may vary depending on the specific project or industry.

Salary Expectations

The salary for a data scientist can vary widely depending on factors such as location, experience, education, and the industry they work in.

According to Glassdoor, the national average salary for a data scientist in the United States is around $118,000 per year. However, the salary can range from around $80,000 to $160,000 or more.

In general, data scientists with more experience tend to earn higher salaries. For example, a data scientist with 5-9 years of experience can expect to earn around $130,000 per year, while a data scientist with 10-19 years of experience can expect to earn around $145,000 per year.

Location also plays a big role in determining salary. Data scientists working in major tech hubs such as San Francisco, New York, and Seattle tend to earn higher salaries than those working in other parts of the country.

Education level and the specific industry can also impact salary. Data scientists with a PhD or Master’s degree tend to earn higher salaries than those with just a Bachelor’s degree. Data scientists working in finance, technology, and healthcare tend to earn higher salaries than those working in other industries.

It’s important to note that the salary for a data scientist is a moving target, as the field is growing fast and changing rapidly. The salary also depends on how data science is positioned in the company, size of the company, level of seniority and the specific role in the company.
