Data science is an emerging field, and those with the right data scientist skills are doing. According to the Bureau of Labor Statistics, career opportunities in this field are anticipated to grow 19% by 2026, much faster than average.

While not all successful data scientists have college degrees, a majority of them have at least a bachelor’s degree in the data science field. Many of them also have graduate degrees, including master’s, Ph.D., and/or graduate certifications.

What Kind of Skills Do You Need to Be a Data Scientist?

“Data scientist” is a broad term that can refer to a number of different careers. Generally, a data scientist analyzes data to learn about scientific processes, market trends, and risk management.

Some job titles in data science include data analyst, data engineer, computer and information research scientist, operations research analyst, and computer systems analyst.

Data scientists work in a variety of industries, ranging from tech to medicine to government agencies. The qualifications for a job in data science vary because the title is so broad. However, there are certain skills employers look for in almost every data scientist. For example, data scientists need strong statistical, analytical, reporting skills, and more.

Types of Data Scientist Skills

Analytical Skills

Perhaps the most important skill for a data scientist is to be able to analyze information. Data scientists have to look at, and make sense of, large amounts of data. They have to be able to see patterns and trends and have an idea of what those patterns mean. All of this takes strong analytical skills.

  • Big Data
  • Constructing Predictive Models
  • Creating Controls to Assure Accuracy of Data
  • Critical Thinking
  • Data Analysis
  • Data Analytics
  • Data Manipulation
  • Data Wrangling
  • Data Science Tools / Data Tools
  • Data Mining
  • Evaluating New Analytical Methodologies
  • Interpreting Data
  • Metrics
  • Modeling Data
  • Modeling Tools
  • Producing Data Visualizations
  • Research
  • Risk Modeling
  • Testing Hypotheses

Open-Mindedness

Being a good data scientist also means being creative. First, you have to have an open mind in order to spot trends in data. Secondly, you need to make connections between data that might seem unrelated to someone that is biased. This takes a lot of open-mindedness. Finally, you need to explain this data in ways that are clear to the executives at your company. This often requires creative analogies and explanations.

Communication

Data scientists not only have to analyze data, but they also have to explain that data to others. They must be able to communicate data to people of different skill sets, explain the importance of patterns in the data, and suggest solutions. This involves explaining complex technical issues in a way that is easy to understand. Often, communicating data requires visual, oral, and written communication skills.
