Want to be a data scientist? You’ve hit on a growth career, if so: according to the U.S. Bureau of Labor Statistics, employment of data scientists is projected to grow 36% to 2031, which is a much faster rate than the average for all occupations.
It’s a well-paid job choice too, with the median annual wage at $100,910 as of May 2021. Data scientists are in demand as the pace of digitalisation increases, and it has grown over the last 15 years or so as companies and institutions gather – and grapple with – increasing volumes of data, and as AI has grown in importance.
This is the science of gaining useful insights from data. Data scientists use statistics, machine learning and data visualization to analyze large amounts of information and gain new understanding from it. This information is then used by business intelligence and marketing teams, for example, to drive the strategy and direction of a company or a project.
The tools of data science are the data, algorithms and software tools that are used to analyze it. Data comes in a huge amount of forms: unstructured text and images as well as structured numeric information are just a couple. The algorithms involved in a process can be simple or complex—the latter are typically used for supervised learning tasks that involve making predictions based on historical information (known in the industry as “training sets”).
Software is also crucial when it comes to determining which steps need to be taken next. Data scientists use many different types of software – Tableau and Apache Spark are two, and data scientists are often proficient coders. Python is a popular language in the field, as it can be used for data cleaning, manipulation, visualization, and analysis.
