10 skill sets every data scientist should have

• Read original article here

Demand for data science talent is growing, and with it comes a need for more data scientists to fill the ranks. While the application of data science is its own field, it’s not relegated to one industry or line of business. Data scientists can make an impact just about anywhere in any organization.

If you’re a burgeoning data scientist or heading down that path, you know that education is the first step. However, outside of the technical curriculum, there are data science skills that will transcend disciplines. Practicing and developing these skills will help separate you from the crowd of job applicants and scientists as the field grows.

These skills won’t require as much technical training or formal certification, but they’re foundational to the rigorous application of data science to business problems. Even the most technically skilled data scientist needs to have the following soft skills to thrive today.

With this skill, you will:

Critical thinking is a valuable skill that easily transfers to any profession. For data scientists, it’s even more important because in addition to finding insights, you need to be able to appropriately frame questions and understand how those results relate to the business or drive next steps that translate into action.

It’s also important to objectively analyze problems when dealing with data interpretations before you form an opinion. Critical thinking in the field of data science means that you see all angles of a problem, consider the data source, and constantly stay curious.

With this skill, you will:

Effective communication is another skill that is sought just about everywhere. Whether you’re in an entry-level position or a CEO, connecting with other people is a useful trait that helps you quickly and easily get things done.

In business, data scientists need to be proficient at analyzing data, and then must clearly and fluently explain their findings to both technical and non-technical audiences. This critical element helps promote data literacy across an organization and amplifies data scientists’ ability to make an impact. When data offers a solution to various problems or answers business questions, organizations will rely on data scientists to be problem solvers and helpful communicators so that others understand how to take action.

With this skill, you will:

You can’t be a data scientist without the skill or desire to solve problems. That’s precisely what data science is all about. However, being an effective problem solver is as much a desire to dig to the root of an issue as it is knowing how to approach a problem to solve it. Problem solvers easily identify tricky issues that are sometimes hidden, and then they quickly pivot to how they’ll address it and what methods will provide the best answers.

With this skill, you will:

A data scientist must have intellectual curiosity and a drive to find and answer questions that the data presents, but also answer questions that were never asked. Data science is about discovering underlying truths and successful scientists will never settle for “just enough,” but stay on the hunt for answers.

With this skill, you will:

Data scientists perform double duty: not only must they know about their own field and how to navigate data, but they must know the business and field in which they work. It’s one thing to know your way around data, but data scientists should deeply understand the business—enough to solve current problems and consider how data can support future growth and success.

"Data science is more than just number crunching: it is the application of various skills to solve particular problems in an industry," explains Dr. N. R. Srinivasa Raghavan, Chief Global Data Scientist at Infosys.

These are more required skills that you typically see listed closer to the top of job descriptions for data scientists. Many of the areas will be developed and covered in educational courses or formal business trainings. And many organizations are increasingly emphasizing them as their analytics and data staff evolve.

With this skill, you will:

Data preparation is the process of getting data ready for analysis, including data discovery, transformation, and cleaning tasks—and it’s a crucial part of the analytics workflow for analysts and data scientists alike. Regardless of the tool, data scientists need to understand data preparation tasks and how they relate to their data science workflows. Data prep tools like Tableau Prep Builder are user-friendly for all skill levels.

With this skill, you will:

This skill falls in line with the non-technical skills, because it relates to critical thinking and communication. Self-service analytics platforms help you surface the results of your data science processes and explore the data, but they also help you share these results with less-technical people. When you create a dashboard in a self-service platform, end users can tune parameters to ask their own questions and evaluate their impact on the analysis in real time as dashboards update.

With this skill, you will:

This skill is almost a given. Since data scientists are knee-deep in systems designed to analyze and process data, they must also understand the systems’ inner workings. There are many different languages used in data science. Learn and apply the languages that are most relevant to your role, industry, and business challenges.

With this skill, you will:

Much like coding, math and statistics play a critical part in data science. Data scientists deal with mathematical or statistical models and must be able to apply and expand on them. Having a strong knowledge of statistics enables data scientists to think critically about the value of various data and the types of questions it can or cannot answer. At times, problems require the design of novel solutions, which may merge or modify off-the-shelf analytic techniques and tools. Understanding the underlying assumptions and algorithms is critical in using these applications.

With this skill, you will:

Neither machine learning nor AI will replace your role in most organizations. Using them, however, will enhance the value you deliver as a data scientist and help you work better and faster. As one Chief Data Officer recently shared: “In order to realize the promise of AI and machine learning, you’re going to need a number of quintessentially human skills.” As he conveyed, your biggest challenge in AI is knowing if you have the right data, when the ‘right data’ shows the wrong things, and finding ‘good enough’ data for AI before deciding on a trained AI model that will be most useful.
