So you’re wondering how to become a data scientist. You’re not alone. Data science is one of the most exciting fields of the 21st century. With the digitization of many jobs, data scientists will become invaluable in the future. The number of data scientists in the US has grown by 300% over the last four years. And with more and more businesses relying on data science for their daily operations, many people choosing data science as a career can look forward to job demand and job security for a long time to come.
But what is a data scientist and how do you become one?
What is a data scientist?
Data science is a broad and constantly evolving field, But, in general, a data scientist is someone who gathers and interprets data in order to solve a problem or reach a conclusion. This could be through different kinds of modelling, like through graphs spreadsheets. Many data scientists are proficient in creating AI algorithms able to recognize patterns in data and turn them into useful content that can be used to solve problems and draw certain conclusions. For instance, a video streaming service may hire a data analyst to review the company’s data points to see who renews their subscription, who is viewing what, and other metrics. They would then be able to draw certain conclusions about what the business could do with that information.
What education do I need to become a data scientist?
While you don’t technically need any education to become a data scientist, most people in the field have earned at least a BA in IT, computer science, math, physics, or some related field. Many others will go on to do an MA in a similar or related field. Still others go on to get PhDs in data science. If you have your eye on an advanced or senior positions, you will most likely need to get an MA or PhD.
Fields relevant to data science include:
- Computer science
- Social science
- Applied math
Most universities and colleges will offer four-years degree programs in the above.
Do I need any other experience or certifications?
Data scientists can get certified in particular fields like in Cloudera, EMC, and SAS. Many data scientists only choose specializations in particular fields. For example, many people can choose between specializations like applied machine learning and big data ecosystems.
