SAS (Statistical Analysis System) is a trusted software package that researchers and analysts use to make sense of large amounts of data. Think of it as a powerful calculator that can handle millions of data points and create useful reports and charts. Organizations like healthcare companies, research institutions, and government agencies use SAS to understand trends, make predictions, and draw conclusions from their data. While newer alternatives like R and Python exist, SAS remains popular, especially in regulated industries like pharmaceuticals and finance, because it's reliable and has been industry-standard for decades.
