Data science is one of the world’s fastest-growing and most in-demand fields. It uses advanced statistical and computational techniques to analyze data and extract insights to inform business decisions and public policy and solve complex problems. There are various steps you may take to get started if you want to pursue a career in data science. This post will cover what a data scientist is, the difference between a data analyst and a data scientist, what a data scientist does, how to become a data scientist, the skills you need, and popular career paths.
What Is a Data Scientist? Salary, Skills, and How to Become One
A data scientist is a professional who uses data analysis, machine learning, and statistical modeling to extract insights and solve problems. They work with large and complex datasets to identify patterns, trends, and relationships that can inform business decisions. Data scientists are typically responsible for designing experiments, building predictive models, and creating visualizations to communicate insights to stakeholders.
According to Glassdoor, the average salary for a data scientist in the United States is $113,309 per year. However, salaries can vary depending on your experience level, location, and the industry in which you work. Data scientists in finance, healthcare, and technology tend to earn higher salaries than those in other sectors.
Data Analyst vs. Data Scientist: What’s the Difference?
While data analysts and data scientists work with data, the two roles have some critical differences. Data analysts are responsible for gathering, cleaning, and transforming data into a usable format. They also perform introductory statistical analysis and create reports and visualizations communicating insights to stakeholders. On the other hand, data scientists use more advanced statistical and computational techniques to analyze data and extract insights. They also design experiments and build predictive models to make business decisions.
What Does a Data Scientist Do?
A data scientist’s day-to-day tasks can vary depending on their organization and the specific project they’re working on. However, some everyday tasks include:
- Gathering and cleaning large datasets
- Analyzing data using statistical and computational techniques
- Building predictive models
- Creating visualizations that communicate insights to stakeholders
- Designing experiments to test hypotheses
- Collaborating with other professionals, such as software engineers and business analysts
How to Become a Data Scientist
If you’re interested in becoming a data scientist, here are some steps you can take:
- Get a degree in a relevant field: Most data scientists have a degree in an area such as computer science, statistics, mathematics, or engineering.
